Allen County Ohio Fair Festival
Nine August days in Lima belong to the Allen County Fair, run by the Allen County Agricultural Society on the Allen County Fairgrounds at 2750 Harding Highway. Livestock judging, open-class exhibits, harness racing, nightly gospel singing, a midway, and a grandstand bill from band showcases to a demolition derby fill grounds the fair’s own record puts at more than 125 acres. Lima, county seat since 1831, is the fair town as well.
What the Allen County Fair Is
The Allen County Fair is the annual nine-day August fair of the Allen County Agricultural Society, a nonprofit corporation formed under Chapter 1711 of the Ohio Revised Code, governed in the state audit record by an 18-director board serving staggered three-year terms. Its competitive heart is the open-class and Junior Fair programme (livestock: beef, dairy cattle, dairy goats, saddle horses, poultry and waterfowl, sheep and swine; exhibits: agriculture, horticulture and floriculture, family arts and crafts, sewing and needle arts, canned and baked goods, wine, antiques, fine arts and photography; plus Antique Machinery, a Tractor Pull, and a Harness Racing chapter, as the 2024 handbook organises them). Entertainment runs on the grandstand, the Nutrien Plaza Stage, and the Gospel Singing Tent, which the fair’s entertainment layer says holds concerts every night. Fair admission covers that entertainment except for concerts and select grandstand events, which carry their own prices.

From a One-Day Farm Show to Nine Days in Lima
The fair’s own timeline tells its story, gap included. On January 11, 1851, the Society was formed in Lima, and on October 21, 1851, the first fair took place as a one-day event on the Jacobs (Faurot) Farm along the Ottawa River at Lima’s southwest edge, exhibiting farm products and home manufactures. Two-day fairs followed through 1855, then came a five-year absence, in the timeline’s own phrase. The Society reorganised in 1860 and held fairs at the Faurot Farm through 1866. In 1867 the fair moved to the J. B. Roberts Farm, the Lima Driving Park, on 30 rented acres, bought in 1881, sold in 1903 with a 20-year lease retained. Dan Patch set a track record at the fair in 1903.
From 1922 through 1948 the fair was a street fair held with the Delphos Homecoming, styled the Allen County/Tri-County Fair in the anniversary layer. That Delphos era belongs strictly to history: no part of the present fair sits in Delphos. In 1949 the fair used a temporary Showgrounds home on 35 leased acres west of Lima, with 80,000 square feet under canvas. The present grounds date to 1950, when 80 acres east of Lima were purchased, described by the fair’s layers with three different buying agents (the county, the Fair Board, the county commissioners), left unmerged. The first fair there had only a Quonset Hut, earning the name Tent City in that layer.
The grounds then grew building by building, from the 1951 Beef Barn to the 2024 Sheep and Goat Show Arena. The grandstand dates to 1958 (2,000 seats, About layer) and the half-mile racetrack to 1952 (modelled after Delaware’s track, in that layer).
For a useful comparison, see the Adams County Ohio Fair Festival for another county festival.
The fair celebrated 175 years in 2025, in its own words, and its April 30, 2026 letter bills the 2026 fair as the 176th. Those billings are printed here as the fair’s own billings only, never extended to other years, and never turned into an unbroken-run claim. The About page’s 1869 prices (fifteen and twenty-five cents, one-dollar membership, 81 members) are history only.
What to Expect When You Walk Through the Gates
The Show Rings and the Exhibit Halls
Junior Fair exhibitors work the same rings as the open-class competitors, and the Junior Fair Livestock Auction is one of the week’s commercial peaks. The About layer bills that auction as one of the largest Junior Fair livestock auctions in the state (more than 400 sale participants, more than 700 buyers, in that layer), printed here as the fair’s own claim, not a measured ranking. In the exhibit halls, judged rows of produce, crafts, flowers, honey, antiques, and photography hold the county’s year up for comparison.
The Grandstand After Dark
After dark, the grandstand takes over. On Saturday, August 22, 2026, Koe Wetzel performed with special guest Kolby Cooper at 8 p.m.: grandstand and bleacher seats fifty dollars, track seats sixty-five dollars, Party Pit seats seventy-five dollars, none including gate admission, in the fair’s own concert page. On Sunday, August 23, 2026, the Kewpee Showcase of Bands filled the grandstand at 7 p.m., presented in the fair’s April 30, 2026 letter during the 176th fair, while the same Sunday carried the Baton Twirling and Flag Corps Competition at 1 p.m. on the racetrack in front of the grandstand (2026 rules). On Friday, August 28, 2026, the Demolition Derby ran in the grandstand at 7 p.m.: admission eight dollars, children six and under free, infield fifteen dollars for all ages, while the fifty-dollar driver entry fee was a competitor fee, never a spectator price.
The Midway, the Tents and the Park
The fair’s middle ground is Roschman Park, the Nutrien Plaza Stage, the Gospel Singing Tent, and the midway. The Nutrien Plaza Stage, named in the 2023 layer, hosts daytime entertainment, and on Saturday, August 29, 2026, it hosted the Bear Hollow Wood Carvers’ carving auction at 2:30 p.m., closing their August 24 through 29 carving run in Roschman Park in that layer. The remaining 2026 entertainment layers add a Kids Celebration game show, Foam Zone parties, a Wild West showdown, magicians, a tinsmith, a musician, and the TBDBITL (OSU) Alumni Band.
Harness Racing on the Half-Mile Track
Harness racing is the fair’s oldest sporting thread, inside the fair week in the 2026 layer. The USTrotting and Ohio Harness Horsemen’s Association layer lists the Allen County Fair at Lima for August 24 and 25, 2026, at 6 p.m. The state audit record names the Allen County Super Trot, Signature Series Race, as the culmination of the fair’s annual harness racing programme.
Planning Your Visit
Tickets, Passes and Parking
The 2026 gate ladder is the fair’s own and complete, quoted with its year attached. For 2026, daily gate admission was ten dollars for ages seven and over, children six and under free. The 2026 Membership Pass cost thirty-five dollars, on sale December 1, 2025 through August 15, 2026, for county residents aged 18 and over with photo identification, including gate but not grandstand admission. The 2026 Season Pass cost forty dollars through August 20, 2026, and forty-five dollars from August 21 through August 29, 2026, good for all nine days but not the grandstand (ages seven and over). The 2026 Youth Season Pass for ages seven through nine cost twenty dollars through August 20, 2026, and twenty-five dollars from August 21 through August 29, 2026. Parking in 2026 was free on the fairgrounds in the fair’s own words; the thirty-five-dollar figure on the same page is a tow and impound release fee, never a parking price. The 2024 handbook’s ladder agrees on every gate figure.
Midway money sits apart from the gate in the 2026 ticket layer: ride vouchers twenty-five dollars pre-sale, good any day; all-day wristbands thirty-five dollars, discounted pre-sale twenty-five dollars; individual ride tickets one dollar and fifty cents each or twenty for twenty-five dollars (fair week only, in that layer); Kids Day (Monday, August 24) wristbands twenty dollars; Buddy Day (Wednesday, August 26) two wristbands for fifty dollars. The 2024 handbook’s forty-dollar Vendor Pass is a vendor credential in that book’s layer, never a visitor price.
Camping for Exhibitors
Camping at this fair is an exhibitor system, not public camping. The fair’s 2025 camping rules govern camping for livestock and other exhibitors (registration March 1 through August 1; fee two hundred twenty-five dollars; late fee one hundred dollars from August 2 through August 7; no admittance after August 7, in that document). At least one person per camper had to be exhibiting livestock, and Junior Fair livestock exhibitors had first preference. The grounds offered 340 livestock exhibitor spaces plus 63 front spaces for other exhibitors and concessionaires, each with a 30-amp or 50-amp hookup. Campers checked in from Wednesday, August 13, 2025, two days before opening, never a fair day. The 2024 handbook carries a different count in its own layer (310 livestock exhibitor spaces), and the two counts stand unmerged. No 2026 camping rules or fee were published in any layer fetched, so no current fee is printed here, and the 2025 fee must never be carried forward.
Getting Around the Grounds
The ticket layer places handicap parking at Gates 1, 2, and 3 and W, general parking on the north, west, and east sides between State Routes 309 and 117 and the boundary fence, and parking free in 2026. No day-by-day 2026 schedule beyond the dated items here is asserted, since the Schedule page text could not be retrieved; confirm the current year’s daily order from the fair’s own announcements.
Nine Days, Shaped Into a Visit
One satisfying shape opens on a weekday morning among the barns and halls, when judging is under way, then moves to the Nutrien Plaza Stage and Roschman Park in the afternoon, where the wood carvers, the petting zoo, and the daytime entertainers fill the hours between competitions. A visitor with only one day should choose the day whose grandstand event matters most and spend the afternoon walking the barns and the park.
One Day or the Whole Nine
A single day delivers the fair as a spectacle: crowds, midway, one grandstand night, a fast pass through the barns, halls glimpsed rather than studied. The full nine days deliver it as a working agricultural event: the same exhibitors return day after day, judging accumulates into championships and auctions, and mornings in the halls and evenings at the grandstand become familiar.
A Checklist for Fair Week
- Buy the gate pass that matches the visit, and grandstand seats separately
- Confirm the current year’s daily order from the fair’s own announcements
- Arrive in the morning for the halls and judging; keep evenings for the grandstand
- Carry photo identification for a membership pass (2026: county residents aged 18 and over)
- Remember 2026 parking was free; a tow release carried its own fee
- Treat camping as an exhibitor system with preference for livestock exhibitors
- Keep concert, derby, and ride prices apart from the gate
- Allow a full day for barns, halls, park, and one grandstand evening
Beyond the Fairgrounds
The fairgrounds sit east of Lima on Harding Highway, and the city around them gives a fair week its mornings and evenings away from the grounds. As county seat, Lima’s streets already carry the county’s daily business, and a visitor can pair a fair day with an unhurried look at the city before the gates draw the crowds back in the evening.
Why This Fair Still Matters to Allen County
A county fair that has run, in its own documented record, since a one-day show on a farm along the Ottawa River in 1851, matters because it still does the job it was formed to do: gathering the county’s agricultural work where it can be judged, bought, and celebrated. The fair’s history also teaches a useful honesty: its absence, street-fair decades, canvas showgrounds, and Tent City beginning all stand in its own record.

Yes, they have moved from year to year within August: the 2024 handbook run fell August 16 through August 24, the 2025 run August 15 through August 23, and the 2026 run August 21 through August 29, so the next edition’s dates should be expected to shift again.
The Allen County Fair rewards the visitor who treats it as a working fair first and a spectacle second: barns in the morning, halls studied, judging watched, grandstand to close the day. Its record stretches from a one-day farm show in 1851 to a nine-day August gathering on more than 125 acres in Lima, and its own timeline, absence, street-fair years, and Tent City beginning included, is the best guide to what the week means.
