Des Arc was laid out in 1871. According to folk etymology, Des Arc, meaning "the bend", was so named from a big bend in the railroad at the town site. However, the State Historical Society of Missouri believes the name may be a corruption of aux arcs, the origin of the name Ozarks. A post office called Des Arc has been in operation since 1871.
Des Arc was significantly affected by tornadoes on two separate occasions in 2025. On March 14, an EF3 tornado affected the downtown area. On May 16, an EF2 tornado affected much of the same area.
