Bismarck is an unincorporated community between Hot Springs and Caddo Valley on State HWY 7 and 84 in Hot Spring County, Arkansas, United States. Bismarck is an unincorporated rural area. In 2002 the local clinic was closed. As a result, the state of Arkansas declared it an MUA (Medically Underserved Area) and BCHC, Inc. was formed to bring health care to the Bismarck area. Bismarck has three restaurants: DJ's Drive In, La Cabinita, and Pizza Shack.
