Leon David Crestohl, QC (May 7, 1900 – March 21, 1963) was a Canadian lawyer and politician.
Born in Warsaw, Vistula Land (now Poland), the son of Rabbi Hyman Meyer Crestohl (1865–1928), he emigrated with his family to Canada in 1911 living in Quebec City before moving to Montreal in 1919.
During World War II, he served as Crown Counsel for the Wartime Prices and Trade Board in Montreal.
Crestohl was elected to the House of Commons of Canada for Cartier in a 1950 by-election held after the death of the previous MP, Maurice Hartt.
