Douglas Keith Davey, OC (April 21, 1926 – January 17, 2011) was a Canadian politician and campaign organizer.
Davey became a political organizer for the Liberal Party at the constituency level in Toronto in his early 20s, and joined the Executive of the Ontario Young Liberals in the 1950s, along with Judy LaMarsh (later a federal cabinet minister).
Davey was appointed National Campaign Director of the Liberal Party of Canada in 1961.
