Johannes Stark (German: [joˈhanəs ˈʃtaʁk] ^ⓘ; 15 April 1874 – 21 June 1957) was a German physicist who received the Nobel Prize in Physics in 1919 for his discovery of the Stark effect.

A supporter of Adolf Hitler from 1924, Stark was one of the main figures, along with fellow Nobel laureate Philipp Lenard, in the antisemitic Deutsche Physik movement, which sought to remove Jewish physicists from German institutions. In 1947, he was found guilty as a "Major Offender" by a denazification court, but this was reduced to "Lesser Offender" in 1949 after appeal.
