South Lido Park is a Sarasota County park located on Benjamin Franklin Drive. It is a waterfront park on Lido Key just north of Big Sarasota Pass.

The park is located on the former land of Otto Schmidt Zoldan, a pioneer who applied for a homestead at the southern tip of Lido Key in 1904. His claim was granted in 1910 and included most of the land that is now South Lido Park.

Lido Key was originally known as Sarasota Key until the Ringling Isles development in the 1920’s when it was renamed.

Established in 1974, the park features trails, picnic areas, bird-watching, kayaking, and swimming.
