South Dakota Highway 271 (SD 271) is a 25.010-mile-long (40.250 km) state highway in the north-central part of the U.S. state of South Dakota. It connects portions of northeast Walworth County with the northeastern part of Campbell County.

It consists of two disconnected segments. The southern segment extends from U.S. Route 12 (US 12) south of Java to a rural intersection at the Walworth–Campbell county line, northeast of Selby. The northern segment begins at an intersection with SD 10 west of Eureka and ends at an intersection with 102nd Street at the North Dakota state line. Here, the roadway continues as 26th Avenue SE.

The northern segment was previously SD 105 prior to the mid-1970s.
