Dominique Edgard Antoine Potier (2 November 1903 – 11 January 1944) was a Belgian airforce officer during World War II who organised an MI9 escape and evasion network, known as Mission Martin in Belgium and the Possum Line in France.
With the outbreak of World War II, Potier travelled across France, Spain and Portugal and arrived in England in March 1942.
He then joined MI9 and in July 1943 was parachuted into southeast Belgium (Province of Luxembourg) near Suxy, accompanied by a Canadian radio operator Conrad Lafleur.
Initially he was taken to Fresnes prison in Paris, then returned to Reims, where after being subjected to considerable torture, he committed suicide on 11 January 1944.
Potier's remains were exhumed from Reims and, on 18 September 1950, he was reburied with full military honours in the Pelouse d'Honneur Aérienne, Cimetière Communal de B-1140 Bruxelles-Evère.
