The United Kingdom general election debates of 2010 consisted of a series of three leaders' debates between the leaders of the three main parties contesting the 2010 general election: Gordon Brown, Prime Minister and leader of the Labour Party; David Cameron, Leader of the Opposition and Conservative Party; and Nick Clegg, leader of the third largest political party in the UK, the Liberal Democrats. They were the first such debates to be broadcast live in the run-up to a UK election.

A leaders' debate or presidential debate is a public debate held during a general election campaign, where the candidates expose their political opinions and public policy proposals, and criticism of them, to potential voters. They are normally broadcast live on radio, television and the Internet. The events may be organized by media corporations or non-government organizations.
