South Dakota Highway 26 (SD 26) is a 49.540-mile-long (79.727 km) state highway in the central part of the U.S. state of South Dakota. It connects rural areas of Hyde, Hand, and Spink counties.

The highway was established around 1935, replacing SD 22. The segment between SD 45 and SD 47 was added to the path of SD 26 between 1957 and 1962.

An extension of this highway, from US 83 in Onida to SD 47 was proposed in the late 1970s. Although a road was built in this area, it was not designated as part of SD 26.
