Pierre is a small Midwestern city of about 14,000. The seat of Hughes County as well as the state capital, it is a friendly community whose tree-lined streets, historic downtown and lush green parks give way to rolling hills and steep bluffs as the county spreads east into the state’s expansive plains.
Founded in 1880 on the east bank of the Missouri River opposite Fort Pierre, Pierre has been the state capital since South Dakota gained statehood on November 2, 1889. It was chosen for its location in the geographic center of the state. Fort Pierre was named after Pierre Chouteau, Jr., a major American fur trader from St. Louis, Missouri who was of colonial French origin.
Pierre is the principal city of the Pierre Micropolitan Statistical Area, which includes all of Hughes and Stanley counties.
Pierre has a relatively dry, four-season, humid continental climate, with long, dry, cold winters, hot summers, and brief spring and autumnal transitions.
