Clueo (Clue in North America) is a crime fiction board game originally published by Waddingtons in the United Kingdom in 1949. It was devised by Anthony E. Pratt, a solicitor's clerk and part-time clown from Birmingham, England. It is now published by the United States game and toy company Hasbro, which acquired its U.S. publisher Parker Brothers as well as Waddingtons.
