Robert Bilsand McGregor, MBE (born 3 April 1944), nicknamed the "Falkirk Flyer", is a Scottish former competitive swimmer who competed in eight events at the 1964 and 1968 Summer Olympics. He won a silver medal in the 100-metre freestyle in 1964, and finished fourth in the 100-metre freestyle and 4×100-metre freestyle relay in 1968. He was a second favourite for the 1963 BBC Sports Personality of the Year Award. In 2002 he was inducted into the Scottish Sports Hall of Fame. Olympic selectors could not believe that he trained in a 25-metre pool in Falkirk when the selectors arrived to critique him prior to the Tokyo Olympics.
