Robert Stewart Hyndman (June 28, 1915 – November 29, 2009) was a distinguished Canadian portrait and landscape artist based in the National Capital Region.

With war looming, Hyndman returned to Canada in 1939 and joined the Royal Canadian Air Force (RCAF) in June, 1940.

From 1943 until 1944, Hyndman was stationed at Biggin Hill, England and flew Spitfires on bombing runs over the English Channel as part of RCAF 411 Squadron, 126 Wing.

Following his tour retirement (Hyndman flew 155 missions over France and the Netherlands) in September 1944, he was appointed an Official Second World War artist.

Following World War II, Hyndman resettled in Ottawa where he embarked upon a successful career as a painter of portraits and murals.
