Walther Model (pronounced "modal") (January 24, 1891–April 21, 1945) was a German general, and later a Field Marshal, during World War II. He was noted for his defensive skills, and was nicknamed "Hitler's fireman".

A fanatical Nazi, Model served as an infantry officer in World War I. During the Polish and French campaigns in 1939 and 1940 he served as a corps and army chief of staff. In the Russian campaign from 1941 until 1944 he served in succession as a division, corps, and army commander. Model in January 1944 was assigned as commander in chief of Army Group North on the Eastern Front. In mid-August 1944 he was transferred to the west as Commander in Chief West and concurrently as commander in chief of Army Group B. Upon Rundstedt's return as Commander in Chief West in early September 1944, Model retained command of Army Group B, a post he kept until the final dissolution of Army Group B in April 1945. Aware that he would be tried for war crimes, he committed suicide before capture on 21st April 1945. He is buried in the German military cemetery "Der Soldatenfriedhof Vossenack", located near the town of Vossenack, Germany.
