Jacques Marie Charles Trolley de Prévaux (2 April 1888 — 19 August 1944) was a French Navy officer and member of the Resistance. After a brilliant career in the Navy as a pioneer of the Aéronavale and having risen to the rank of captain, he fell out of favour with the Vichy Regime for his sympathies with the Resistance. He became a leader of an intelligence network focused on the Mediterranean, and was eventually betrayed and assassinated by the Nazis, along with his wife, Lotka Leitner. Both were posthumously and jointly made Compagnons in the Ordre de la Libération.
