Colette Marin-Catherine (born 25 April 1929), is a French resistance fighter from Bretteville-l'Orgueilleuse. She joined the Resistance in the summer of 1944 where she was a reconnaissance agent and then a nurse after the Normandy landings; also resistant, her brother Jean-Pierre Catherine was arrested in 1943 and died in the Mittelbau-Dora concentration camp in 1945.
After the war, she pursued memorial work. She rose to prominence when Anthony Giacchino's short documentary Colette, which follows her on a visit to Dora's camp where her brother died, won the Oscar in its category at the 93rd Academy Awards.
