Pollock is a town in Campbell County, South Dakota, United States. The population was 224 at the time of the 2020 census.

Pollock was laid out in 1901 in anticipation of the arrival of a branch of the Soo Line, and named in honor of a first settler with the last name Pollock. The Pollock Depot, a wood-frame former railroad station, is listed on the National Register of Historic Places.

As the roads in the county improved, there was more freight and passenger transportation by truck and automobile. Lower demand for rail freight led to the branch line being partially abandoned.

According to the United States Census Bureau, the town has a total area of 0.32 square miles (0.83 km), all land.
