Resi Pesendorfer (born Theresia Laimer: 21 June 1902 - 31 October 1989) was an Austrian political activist, close during the 1920s to the Social Democrats. With the abolition of democracy during 1933/34 she became a resistance activist opposing Austrofascism and after 1938, opposing Pan-German National Socialism. She organised a highly effective network of women in the Salzkammergut region, taking a lead in the concealment of increasing numbers of army deserters and others with political records which made them targets for the security services.
