Adam Grünewald (born 20 October 1902 in Frickenhausen am Main – died 22 January 1945 in Veszprém) was a German Schutzstaffel officer and Nazi concentration camp commandant. The son of a carpenter who died when he was 8, Grünewald apprenticed as a baker but found work difficult to come by when the First World War ended and the demobilised soldiers entered the labour market. Attracted to the nationalist propaganda prevalent at the time Grünewald joined the Freikorps before signing on with the army for a 12-year stint. Leaving the army as a staff sergeant in April 1931 Grünewald again struggled to find employment and so joined the Sturmabteilung. He rose to the rank of Obersturmbannführer in the SA before switching to the SS shortly after the Night of the Long Knives.
