South Dakota Highway 30 (SD 30) is a 17.077-mile-long (27.483 km) state highway in the east-central part of the U.S. state of South Dakota. It connects the north-central part of Brookings with the northeastern part of it.

SD 30 was established in the mid-1950s. It had two segments, which were connected by the end of the decade. However, most of the highway west of what is now Interstate 29 (I-29) was removed the next decade.
