Franz Leuninger (28 December 1898 – 1 March 1945) was a German trade unionist, politician and resistant against the Nazis' rise to power and regime. Working as a bricklayer after school, he became a member of the trade union for construction workers early on, serving as its regional leader in Silesia in the 1920s. He was a member of the city council of Breslau for the Zentrumspartei from 1930, and ran for the German Reichstag in 1933, as a strong opponent of the Nazi party.
