John Ashford Renshaw Starr (6 August 1908 – 1996), code names Emile and Bob, was a British artist and an agent in France of the United Kingdom's clandestine Special Operations Executive (SOE) organization during World War II. He was the organiser (leader) of the Acrobat network (or circuit) which operated in Dijon. The purpose of SOE in occupied France was to conduct espionage, sabotage and reconnaissance. SOE agents allied themselves with French Resistance groups and supplied them with weapons and equipment parachuted in from England.
Starr was wounded and captured by the German SS on 18 July 1943 and imprisoned for the remainder of the war. After World War II, Starr was accused by several other SOE agents of collaboration with the Germans while he was a captive. John Starr's brother George Starr was also an SOE agent.
