Jacques Desoubrie (1922 – 1949) was a double agent who worked for the Gestapo during the German occupation of France and Belgium during World War II.
He infiltrated resistance groups, such as the Comet Line, and was responsible for the arrest of several leaders and more than 100 members of organizations (called "lines" or "reseau") helping Allied airmen who had been shot down or crash-landed to evade German capture and escape occupied Europe.
After the war he was tried, convicted, and executed in France.
