The 2009 North West 200 Races took place on Saturday 16 May 2009 at the 8.966 mile circuit, dubbed "The Triangle", based around the towns of Coleraine, Portrush and Portstewart, in Northern Ireland. The 2009 race week was the 80th anniversary of the festival, when Malcolm McQuigg, Harry Meagen and Ernie Nott picked up the race wins in 1929.
Steve Plater and William Dunlop took double victories at the meeting, with Alastair Seeley winning the other race held. Two races were cancelled due to adverse weather conditions.
