The Douglas Circuit was a motor racing street circuit in Douglas, the capital and largest town of the Isle of Man and was re-configured each year until 1937.{{cite web|url=http://www.kolumbus.fi/leif.snellman/t4.htm#DOUGLAS|title=Douglas Circuit - Isle of Man|publisher=Leif Snellman|date=|accessdate=April 26, 2014|archive-date=February 7, 2013|archive-url=https://web.archive.org/web/20130207225125/http://www.kolumbus.fi/leif.snellman/t4.htm#DOUGLAS|url-status=dead}} The first Grand Prix, titled "Mannin Beg & Mannin Moar" (English: Small Man & Big Man) was held in 1933 on a {{cvt|4.60|mi|km|abbr=on}} street circuit {{cite web|url=http://www.isle-of-man.com/manxnotebook/fulltext/cd1935/course.htm |title=Douglas Circuit - From "The Circuit Dust, 1935"|publisher=isle-of-man.com|date= |accessdate=April 26, 2014}} which repeated as II and III Mannin Moar on different circuit layouts until 1935. In 1936 the circuit changed again for the IV RAC International Light Car Race and a last time for the (1937) V RAC International Light Car Race.

Racing at Douglas resumed in post-war 1947 on the 1936 {{cvt|3.87|mi|km|abbr=on}} circuit configuration{{Cite web|url=http://www.silhouet.com/motorsport/tracks/douglas.html|title=Douglas Track Info|last=Galpin|first=Darren|website=www.silhouet.com|access-date=2017-12-29}} with the first Manx Cup and the 9th British Empire Trophy. This circuit variant remained largely unchanged until 1953, the 15th British Empire Trophy and last event held on the Douglas street circuit.
