The Division of Corio is an Australian electoral division in the state of Victoria. The division was proclaimed in 1900, and was one of the original 65 divisions to be contested at the first federal election. Named for Corio Bay, it has always been based on the city of Geelong, although in the past it stretched as far east as the outer western suburbs of Melbourne. The current Member for Corio, since the 2007 federal election, is Richard Marles, the current Deputy Prime Minister of Australia.
