Eduard Krebsbach was a former German physician and SS doctor in the Nazi concentration camp in Mauthausen from July 1941 to August 1943. He was executed for atrocities committed at the Mauthausen camp.

Mauthausen was a Nazi concentration camp on a hill above the market town of Mauthausen, Upper Austria. It was the main camp of a group with nearly 100 further subcamps located throughout Austria and southern Germany. The three Gusen concentration camps in and around the village of St. Georgen/Gusen, just a few kilometres from Mauthausen, held a significant proportion of prisoners within the camp complex, at times exceeding the number of prisoners at the Mauthausen main camp.
