Jefferson County Fair

Step into a tradition that has been part of Fairfield since 1851 at the Jefferson County Fair, returning June 22 through June 29, 2026 at the Jefferson County Fairgrounds. This week-long celebration captures the heart of a true 4-H and FFA fair, where livestock shows, youth exhibits, entertainment, and classic fair favorites come together in a setting that still feels welcoming and close-knit. Free front gate admission and free parking make it one of the most accessible fairs in the state, and once you arrive, it is easy to see why a quick visit often turns into a full day spent soaking in the tradition.
