Greene County Ohio Fair Festival
For one week each August, the fairgrounds on Fairground Road in Xenia fill with livestock and grandstand noise. The Greene County Fair is a seven-day Sunday-to-Saturday fair in the county seat, run by the Greene County Agricultural Society, and its 2026 edition was billed the 187th. Its 2026 gate was a flat ten dollars, its harness nights cost nothing extra, and its history refuses one tidy date.

About the Fair in Xenia
The Greene County Fair takes place at the Greene County Fairgrounds, 120 Fairground Road, Xenia, Ohio. Xenia is the county seat of Greene County and the town that hosts the fair. The organiser is the Greene County Agricultural Society, a county agricultural society corporation formed under Chapter 1711 of the Ohio Revised Code. The Greene County Expo Center is the same grounds under its year-round events identity; it is a venue identity, never the fair’s organiser. The Fair Board, the Senior Fair Board, and the Junior Fair Board appear in the fair book as working forms, and none replaces the Society as organiser. Greene County itself is not financially accountable for the Society.
In 2026 the fair ran Sunday, August 2 through Saturday, August 8, opening at 8:00 in the morning and closing usually around 10:00 at night. Friday, July 31 and Saturday, August 1 were pre-fair arrival days, and Sunday, August 9 project pick-up was a release day, not an eighth fair day. Membership is open to county residents eighteen and over, with daily entry and a Senior Fair Board vote.

A History Told in Layers, Not One Date
The Society is first mentioned in the Commissioners’ Journal in June 1833, when notice was ordered of a meeting at the Xenia courthouse to organise an agricultural society to be entitled the Greene County Agriculture Society, in that notice’s quoted wording. The fair-side history records that the Society was officially organised on July 30, 1834. The state audit record records the Society as founded in 1839 to operate an annual agricultural fair. The three layers stand unreconciled.
The first fair is just as layered. One fair-side timeline dates the first fair to 1837, considered by many to be the oldest fair west of the Alleghenies. The fairgrounds history page instead says the first recorded fair was held in and around the courthouse square in 1839, which makes the 2017 fair the 178th, and says the fair as it is known today is said to be the oldest fair west of the Alleghenies. Neither wording is printed here as a verified ranking. The 187th billing for 2026 steps year for year with the 178th billing for 2017, and the two billings are recorded as a consistent chain of billings only; no founding year for the fair is derived from them, and no continuous run is proved from them.
For a useful comparison, see the Geauga County Ohio Great Geauga County Fair Festival for another county festival.
The grounds carry their own layered story. In the fair’s second year the Society leased land near Xenia on Columbus Pike, where the fair was held for the next thirteen to fourteen years. In 1867 the Society bought 36.30 acres of the present grounds, against a secondary layer’s more than 38 acres; neither is a surveyed current size. In April 1886 land was platted as the Fairground Addition to the city of Xenia, while the same history page dates a rival-fair episode to 1884, when a new society called the Union Agricultural Society held its own exhibition at Jamestown and two fairs were held in the county. Its dates are printed as given, never tidied into one year. In 2000 a tornado destroyed seventeen buildings on the fairgrounds, and the fair was rebuilt by July 2001.
What to Expect
The livestock week across three barns
Livestock is the centre of the fair week. Cattle, swine, sheep, goats, poultry, rabbits, horses, llamas and alpacas, and dogs are shown across Barns 1, 2, and 3 and the Horse Arena, with open-class departments in the Exhibitor’s Hall and the royalty coronation in the Assembly Building. Sunday opens with rabbit, Western horse, swine, dairy, and poultry judging, before the royalty coronation, the opening ceremony, and the calf scrambles. Friday closes the livestock business with the Live Champion Livestock Sale at Barn 1.
Two harness racing nights at no cost
Harness racing is the fair’s standing racing signature, run under national and state racing rules with colt stakes. In 2026 the schedule page marked both harness racing nights, Wednesday, August 5 and Thursday, August 6, at 6:30 in the evening, as no cost at the grandstand, and that schedule layer governs. The speed programme printed inside the 2026 book is dated Wednesday and Thursday, July 30 and 31, 2025, and its named races belong to that 2025 layer; no 2026 race card, purse, or named memorial race is printed from it here.
Grandstand nights, pulls, and the midway
Monday, August 3 brings the DerbyDog demolition derby, grandstand five dollars and infield fifteen dollars. Tuesday, August 4 brings KOI drag racing, grandstand five dollars and infield ten dollars. Friday, August 7 brings the OSTPA truck and tractor pulls, grandstand five dollars and infield ten dollars. Saturday, August 8 closes with the Sullivan Motorsports truck pull, grandstand five dollars and infield ten dollars. Those grandstand figures are component prices, never gate admission, and the schedule page governs every date printed here. All week the fairgrounds carry the Monkey Riding Dog Show, the Goat Island Petting Zoo, and the Old Timers Club Displays, with additional acts still to be announced; no 2026 concert act is named fair-side, and none is invented here. The midway runs its own money: wristbands at twenty-two dollars, a Wednesday Family Day special at sixteen dollars, Friday and Saturday armbands at eighteen dollars when purchased between 1:00 and 5:00 in the afternoon and twenty-two dollars after, and single tickets at two dollars twenty-five cents each, ten for twenty-two dollars, twenty for thirty-five dollars, and fifty for eighty-five dollars. No midway operator is named fair-side.
Planning Your Visit
Tickets, re-entry, and the three discount days
The 2026 ladder agrees in both its layers: daily gate admission ten dollars, children five and under admitted free with a paying adult, a seasonal ticket at forty dollars, and a membership ticket at thirty dollars. Single-day tickets admit once; weekly and membership tickets allow re-entry. The Ohio ladder is a flat ten-dollar daily gate with no child tier at all; no price for children aged six to eleven exists in any Ohio fair-side layer fetched, and none is supplied. Three discount days in 2026 each carry their own condition: Monday, August 3 is Military Discount Day, five dollars with a military identification card; Wednesday, August 5 is Family Day and Food Pantry Discount Day, five dollars with a non-perishable food item; Thursday, August 6 is Senior Citizen Discount Day, five dollars. Those five-dollar gates are conditional discount-day gates, never a general five-dollar admission. Exhibitor money is kept apart from visitor prices: Mini and Junior Exhibitor Tickets at fifteen dollars, a ten-dollar 4-H and FFA open-class entry layer, a ten-dollar Meal Deal, and harness entry fees of one hundred, seventy-five, and thirty dollars for the colt stakes, Signature Series, and ladies driving series. No earlier year’s Ohio ladder was fetched, so the 2026 ladder is never printed as any other year’s.

Parking and camping under the fair book’s rules

General parking is free outside the Main Fair Entrance; reserved parking at forty-five dollars sits behind the barns and in the Assembly Building lot. Fair-week camping is a ruled, pass-based system in the 2026 book, and no fair-week camping price was fetched from any fair-side layer, so none is printed. Each person camping must show proof of a weekly ticket in their name, a membership ticket in their name, or a current Greene County Agriculture Pass issued to 4-H and FFA members, advisors, and species workers, together with a camping pass carrying a camping number. No camping permits are given out until passes are purchased, sub-letting is prohibited, and the purchaser must occupy the space. No one under nineteen may stay in a camper without adult supervision, and no pets or open campfires are allowed. Back-row campers must be in place by dark on Thursday and front-row campers by Friday before the fair. The camping waiting list moves very slowly, the book warns. The Expo Center’s year-round event camping, with pets welcome and fire rings permitted, is a different system, never merged here.
A Wednesday in the Middle of Fair Week
Wednesday, August 5, 2026 shows the fair at full stretch. The morning belongs to market poultry and goat shows and peewee swine showmanship. Midday brings the Diaper Derby and Family Night with sixteen-dollar ride wristbands, and the afternoon brings the 4-H awards, celebrity swine showmanship, and the memorial hog show. The evening closes at the grandstand with harness racing at no cost at 6:30. Arrive at the 8:00 opening, work the barns and the Exhibitor’s Hall before the afternoon heat, take the Family Night ride prices after 4:00, and finish at the grandstand.
The Fair Against Its Own Past
The early fair was a three-day event with Main Street horse racing; the 2026 fair is a seven-day week with grandstand harness racing and closing truck pulls. The first recorded fair sat around the courthouse square; the present fair sits on grounds bought in 1867 and platted as the Fairground Addition in 1886. The 2000 tornado destroyed seventeen buildings, and the fair was rebuilt within a year. The season itself moved from August-to-October dates to the last days of July and the first week of August; the 2026 run sits wholly in August. What has not changed is the shape of the week: livestock judging across the barns, a royalty coronation, harness racing, and a closing sale.

Beyond the Fairgrounds
The courthouse square at 45 North Detroit Street is the seat of the county and the historic home of the first recorded fair, and the county is named for Revolutionary War General Nathanael Greene. Jamestown’s role is historic only, as the rival 1880s exhibition town; no other Greene County community hosts any part of this fair. The fairgrounds’ year-round expo life is separate from fair week, and its events are never the fair’s programme.
Why the Fair Still Matters
The Greene County Fair matters because it is still, at its centre, a youth and livestock fair. The Junior Fair week, the 4-H and FFA entries, the royalty coronation, the showmanship contests, and the Friday champion sale teach young people to raise, show, and sell an animal, while the open-class halls carry the household arts of the adults who judge and teach them. The harness racing nights, free at the grandstand in 2026, keep the racing tradition the audit record names as the fair’s culminating event. The fair’s history, with its conflicting first-fair years and hedged oldest-fair claim, is itself a kind of honesty: a fair held, moved, rivalled, blown down, and rebuilt needs no single settled birthday to matter to its county.
Frequently Asked Questions
Where is the Greene County Fair held?
At the Greene County Fairgrounds, 120 Fairground Road, Xenia, Ohio, the county seat and host town; the organiser is the Greene County Agricultural Society.
What does admission cost in 2026?
Ten dollars at the gate, children five and under free with a paying adult, forty dollars seasonal, thirty dollars membership. Three discount days offer five-dollar entry with conditions: Monday with military identification, Wednesday with a food item, Thursday for seniors. Single-day tickets do not allow re-entry; weekly and membership tickets do.
Is there harness racing, and does it cost extra at the grandstand?
Yes, and in 2026 it cost nothing extra: both harness nights, Wednesday, August 5 and Thursday, August 6 at 6:30, were marked no cost at the grandstand. The derby, drag racing, and truck pulls carry their own grandstand and infield prices, never gate admission.
Can visitors camp at the fairgrounds during fair week?
Camping during fair week is a ruled, pass-based system under the 2026 book, not an open public campground. Each camper must show a weekly ticket, membership ticket, or current Agriculture Pass in their name, plus a camping pass with a camping number, and no permit is issued until passes are purchased. No pets or open campfires are allowed, and no fair-week camping price was published, so none is printed here.
What to Expect From the Next Greene County Ohio Fair Festival
How often is Greene County Ohio Fair Festival held?
Once a year, as a seven-day fair in late July and early August, running Sunday through Saturday.
When is the next Greene County Ohio Fair Festival?
The next edition follows the annual late-summer pattern: the 2026 fair ran August 2 through August 8, billed the 187th. Exact dates are announced by the fair each year and are never carried forward from a previous run.
Will the dates change?
Yes, within the late-summer pattern: 2024 ran July 28 through August 3, 2025 ran July 27 through August 2, and 2026 ran August 2 through August 8, so no single run of days is permanent.
The Greene County Fair in Xenia is best approached as its record presents it: a Society-run August fair on Fairground Road, with a flat ten-dollar gate, two free harness nights, a full livestock week, and a history honest about its own conflicting layers. Come for the barns in the morning, the grandstand in the evening, and the sale on Friday.
