The Football World Championship, also known as the United Kingdom Championship or the International Club Championship, was a exhibition association football match played between the English and Scottish club champions on a regular, but not annual, basis in the late 19th and early 20th centuries, with varying degrees of press attention and public interest. Perhaps the most widely publicised at the time under the 'World Championship' name was the 1888 event between Renton and West Bromwich Albion, while in the modern age interest from historians has drawn more attention to matches involving Sunderland, particularly the 1895 match. The FA Cup and Scottish Cup were qualification of the tournament.

The 1888 World Championship was an exhibition football match that took place in Crosshill, Scotland, on 19 May 1888 between the winners of the Scottish Cup, Renton, and the English FA Cup, West Bromwich Albion. The match was won by Renton who beat Albion 4–1. The match was played in very bad weather and a replay in England was proposed, but never took place.
