Since 1992, this annual town festival has been held each summer, dedicated to the region's "agricultural jewel", Olathe Sweet Corn. The Festival features such entertainment as craft shows, karaoke, local acts, like the Anders Brothers, and concerts by bigger names like Three Dog Night in 1996, Kansas in 1998, Styx in 2004, and LeAnn Rimes in 2007, among many others. Any proceeds go to local non-profit groups.
