Dierks was formerly known as "Hardscrabble". It was then changed to "Dierks" after Hans Dierks, the oldest of four brothers who owned the Dierks Lumber and Coal Company. In 2007, Dierks celebrated its 100th birthday.
Severe thunderstorms that moved through southwest Arkansas on April 9, 2009, produced an EF3 tornado that destroyed the city's water treatment plant. A training technician from the Arkansas Rural Water Association helped the utility operators establish a temporary connection to the neighboring Nashville Rural Water System until the National Guard could deliver a pair of portable water purification systems. The Boy Scouts of America helped to give water bottles to families that were on the city water.
A smaller tornado in 2010 hit the local laundromat and tore down a few power lines. No injuries or deaths were reported.
