The Anna Carr Homestead, located off South Dakota Highway 20 in or near Bison, South Dakota, is a historic sod house which was built in 1907. It was listed on the National Register of Historic Places in 1978.
It is a one-story sod house that, when listed, had a wood addition to its rear, from a later date. The original residence is in plan and had a flat roof. The sod walls were tall, made of sod strips about square and high. An addition to the house served as a post office for a time.
