About Washington County Fair

Marietta is home to the Washington County Fair, which celebrates the agricultural heritage of the Ohio River valley at the confluence of the Ohio and Muskingum Rivers. Founded in 1850, it stands as one of Ohio's most enduring agricultural fair traditions. A harness racing card is part of the week's schedule.
