Running with Scissors (RWS) is an American video game developer based in Tucson, Arizona. It was founded in 1996 by Vince Desi through a business decision of Riedel Software Productions, a maker of child-friendly games.

RWS created and maintains the Postal franchise, which has often caused controversy for its use of violence. RWS' first game was Postal in 1997, which caused much controversy and a trademark lawsuit from the United States Postal Service that lasted until 2003. A potential second game, Flesh and Wire, was canceled in 1999. The company followed up Postal with Postal 2 in 2003. The third game in the series, Postal III, was co-developed by RWS and an internal team of publisher Akella, and RWS distanced itself from the game due to poor critical reception. RWS most recently worked on Postal 4: No Regerts, which was released in 2022, and the spin-off Postal: Brain Damaged.
