Saturday in the Park is an annual festival that is held at the Grandview Park Municipal Bandshell in Sioux City, Iowa. Started in 1991, the festival falls on the Saturday closest to the 4th of July and attracts around 25,000 people from all over the Midwest for the weekend. The festival coincides with an annual pilgrimage of representatives from Sioux City’s sister city, Lake Charles, Louisiana, adding a Mardi Gras-inflected Cajun accent.

Saturday in the Park is one of the premier festivals in the upper Midwest and is best known for its eclectic mixture of musical traditions. Live music acts are offered throughout the day at one of two stages located within the park.
