About Mule Day

Mule Day is a long-running community festival in Columbia, Tennessee, centered on mules, local heritage and a multi-day program of shows, markets, music and a parade. The City of Columbia describes it as a signature local tradition rather than a nationwide statutory observance.

For 2026, the official organizer schedules the main festival program for April 9–11, with the downtown parade at 11:00 a.m. on April 11 and related wagon activities beginning earlier that week. Future editions should be checked against the organizer’s target-year schedule.

Why Mule Day matters

Mule Day celebrates Columbia’s historic relationship with mule breeding, agricultural trade and community festival traditions. Its modern program combines animal events with entertainment, crafts, food and local gatherings.

Participation should follow organizer, venue and animal-health rules. A festival guide is not a substitute for veterinary, equine-handling, parade-entry or traffic-control instructions.

History of Mule Day

The City of Columbia says the tradition began in the 1840s as “Breeder’s Day,” a one-day livestock show and mule-market event held on the first Monday in April.

The city identifies 1934 as the first “official” Mule Day, consisting of a parade and a mule show in downtown Columbia. The event later expanded from a single day into a multi-day festival.
