The Corn Palace, commonly advertised as The World’s Only Corn Palace and the Mitchell Corn Palace, is a multi-purpose arena/facility located in Mitchell, South Dakota, United States. 

The Moorish Revival building is decorated with crop art; the murals and designs covering the building are made from corn and other grains, and a new design is constructed each year. Up to 500,000 people visit the Corn Palace each year, making it a well-liked tourist destination.

The Corn Palace serves the community as a venue for concerts, sports events, exhibits, and other community events. Each year, the Corn Palace is celebrated with a citywide festival, the Corn Palace Festival. 

Historically, it was held at harvest time in September, but recently it has been held at the end of August. Other popular annual events include the Corn Palace Stampede Rodeo in July and the Corn Palace Polka Festival in September. It is also home to the Dakota Wesleyan University Tigers and the Mitchell High School Kernels basketball teams.
