The 1966 United Kingdom general election happened on 31 March 1966. The Labour Party won with a landslide win. The Prime Minister Harold Wilson stayed in power.

Wilson decided to call a snap election because his government had a small majority. This made it hard for them to make new laws. This was the last general election with a voting age of 21. After the Representation of the People Act, 18 year-olds were allowed to vote in elections.
