The Fair

Every year, Hannibal hosts the Marion County Fair, which is one of Missouri's premier county fairs, running eight days from late July into August in the hometown of Mark Twain on the Mississippi River. Drawing visitors from across northeast Missouri and beyond, the fair takes on an added glow in a city already famous for its literary heritage.

Local Tips

Hannibal's Mark Twain sites — the boyhood home, the cave, and the museum — are all nearby and make for an ideal companion to a fair visit, especially with children.

What You'll Find There

Expect a full complement of livestock shows, 4-H competitions, carnival rides, fair food, demolition derbies, and grandstand entertainment over eight festive days beside the Mississippi.
