Wisden Cricketers' Almanack, or simply Wisden, colloquially the Bible of Cricket, is a cricket reference book published annually in the United Kingdom. The description "bible of cricket" has been used for Wisden since the early 1900s. In October 2013, an all-time Test World XI was announced to mark the 150th anniversary of Wisden Cricketers' Almanack.

John Wisden was an English cricketer who played 187 first-class cricket matches for three English county cricket teams, Kent, Middlesex and Sussex. He is now best known for launching the eponymous Wisden Cricketers' Almanack in 1864, the year after he retired from first-class cricket.
