The Lonely Londoners is a 1956 novel by Trinidadian author Samuel Selvon. Its publication was one of the first to focus on poor, working-class black people following the enactment of the British Nationality Act 1948 alongside George Lamming's (1954) novel The Emigrants. The Lonely Londoners was included on the "Big Jubilee Read" list of 70 books selected by a panel of experts, and announced in April 2022 by the BBC and The Reading Agency, to celebrate Queen Elizabeth II's platinum jubilee in June 2022.

Samuel Selvon was a Trinidad-born writer, who moved to London, England, in the 1950s. His 1956 novel The Lonely Londoners is groundbreaking in its use of creolised English, or "nation language", for narrative as well as dialogue.
