Capital of South Dakota
Pierre is the capital of South Dakota, a state in the Great Plains region of the United States. Despite being the seat of state government, Pierre is a small city. In fact, it is one of the least populous state capitals in the entire country.
Chosen for Its Location
Pierre became the capital largely because of where it sits. The city lies almost exactly in the geographic center of South Dakota, on the bank of the Missouri River. When South Dakota became a state, that central position made Pierre a practical and fair choice for the capital, easy to reach from all corners of the state.
A Quiet Capital on the River
Pierre is unusual among state capitals for its small size and quiet character. The Missouri River, one of the great rivers of North America, runs right past the city. The name "Pierre" comes from an early fur trader, a reminder of the days when the area was a frontier trading region. The city remains a calm, modestly sized seat of government rather than a sprawling metropolis.
