List of association football teams to have won four or more trophies in one season
This is an incomplete list of football clubs which have won four or more trophies in a single season.
In a football season, clubs typically compete in a number of domestic competitions, such as a league and one or more cup competitions, as well as sometimes in continental competitions. Winning multiple competitions is seen as a particularly significant achievement. Doubles and trebles are usually long-remembered achievements, but do occur with some level of frequency, whereas winning four or more trophies in one season is much rarer. In the 2010s, the terms quadruple, quintuple and sextuple have sometimes been used to refer to winning four, five and six trophies in a single season.
This list is limited to clubs playing in the top division of their league system.
