Charlotte "Lotte" Hedwig Hahm (born 23 May 1890 in Dresden; died 17 August 1967 in Berlin) was a prominent activist of the lesbian movement in Berlin during the Weimar Republic, National Socialist period, and after 1949, in the Federal Republic of Germany.

Hahm was committed to organising lesbian women and improving their social situation. She was especially known for her organizing activities. Together with Käthe Reinhardt, she ran the largest lesbian clubs of the time in the 1920s, with up to 2,000 members and 500 participants, as well as various bars. She also wrote articles, organized lectures, readings and excursions, and supported the establishment of lesbian networks in other cities. In 1929 she was co-founder of the "Transvestite Association D'Eon", world's first organization of transgender people.
