Günther Kaufmann (16 June 1947 – 10 May 2012) was a German film actor best known for his association with director Rainer Werner Fassbinder. Fassbinder directed Kaufmann in a total of 14 films, casting him in leading and minor roles. Kaufmann was also romantically involved with the director for a time.

In 2002, Kaufmann was accused of murder in relation to the 2001 death of Hartmut Hagen, a 60-year-old accountant whom Kaufmann's wife had defrauded. The death was ruled accidental, but Kaufmann was sentenced to prison for lesser crimes relating to the incident. In 2005, a new police investigation discovered that Kaufmann was innocent, and had confessed to the crimes to cover up for his late wife, who may have been the perpetrator. He was subsequently released from prison and resumed his acting career.
