Mud Island had been formed by a buildup of silt, gravel, and sand by 1899. It was originally referred to as City Island until the 1950s. Mud Island became the location of the Memphis Downtown Airport in 1959 and was used primarily by wealthy businessmen to access Downtown Memphis. In 1960, the Wolf River Levee was used to divert the flow of the Wolf River. The airport was shut down in 1970 due to the construction of the Interstate 40 bridge. In 1976, the architect responsible for the Memphis International Airport and Memphis College of Art came up with a project to turn 50 acres (20 hectares) of property owned by the city into a destination designed to attract locals and tourists alike. The proposed name for the park was Volunteer Park, but it was later named Mud Island Park when it was opened on July 4, 1982.

The park has been run by several different groups including the Park Commission, The Parks Division, Sidney Shlenkner, and the RDC (Riverfront Development Corporation). The RDC is being in charge of running the park since 2000.

On October 1, 2020, a break-in at the Mississippi River Museum was reported to police. Over $50,000 worth of historical artifacts were stolen shortly after the museum shut down due to the COVID-19 pandemic. The burglar(s) have yet to be found as of February 2021.

On Sunday, January 23, 2021, human bones were found scattered in an area of tall grass near the large Memphis sign, located on the southern end of the peninsula, by a landscaping crew. The remains were found in an area that tends to be covered with water at different points in the year, and the police stated the remains may have washed up from the Mississippi River, but it is still unknown at this point. The police have yet to release any further information on the case as of February 21, 2021.
