Bennett County

Bennett County is an administrative division in eastern South Dakota with gently rolling hills and deep erosion gullies. The Little White River flows through the central southern area, shaping the landscape around Martin, the county seat.

The region was established in 1909 when land was separated from Fall River County. The first county commission took office following elections in April 1912.

The demographic composition of Bennett County reflects a strong Native American presence, with over 60 percent of residents identifying as American Indian as of 2020.

The county administration in Martin offers services such as government offices, public records, and property assessments for residents. Visitors can easily find basic administrative facilities and local services there.

The area contains the North American pole of inaccessibility, the geographical point furthest from any ocean coastline. This location is marked on maps but remains largely unnoticed by most travelers passing through.
