Mr Brown, prime minister since 2007, said he wanted a successor to be in place by the time of the party's conference in September.
Mr Brown announced his intention to quit in a statement in Downing St in which he also said his party was to start formal talks with the Lib Dems.
The Conservatives won the most seats and most votes in the election and have been in talks with the Lib Dems.
Mr Brown said Britain had a "parliamentary and not presidential system" and said there was a "progressive majority" of voters.
