100 Great Black Britons is a poll that was first undertaken in 2003 to vote for and celebrate the greatest Black Britons of all time. It was created in a campaign initiated by Patrick Vernon in response to a BBC search for 100 Greatest Britons, together with a television series (2002), which featured no Black Britons in the published listing. The result of Vernon's campaign was that in February 2004 Mary Seacole was announced as having been voted the greatest Black Briton. Following the original poll, 100 Great Black Britons was re-launched in 2020 in an updated version based on public voting, together with a book of the same title.
