South Dakota Highway 11 (SD 11) is a 77.724-mile (125.085 km) state highway in eastern South Dakota, United States. It connects the northern part of the Sioux City metropolitan area with the Sioux Falls metropolitan area.

The highway originally traveled on the current path of SD 115 in Sioux Falls and Dell Rapids, and ended north of Elkton. In the 1930s, SD 11 was shifted to its current alignment; part of the highway became SD 13. The southern segment was added between 1962 and 1971. Part of the highway in Sioux Falls was changed in the early 1990s. The segment between SD 46 and US 18 was added in the 1990s.
