List of association football teams to have won four or more trophies in one season
In a football season, clubs typically compete in a number of different competitions: usually a domestic league and at least one cup competition, as well as sometimes competing in continental football, that is, the tournaments organised by one of FIFA's six confederations. Winning multiple competitions is seen as a particularly momentous achievement.
Doubles and trebles are usually long-remembered achievements, but do occur with some level of frequency. By contrast, winning four or more trophies in one season is exceptionally rare. In recent years, the terms quadruple, quintuple and sextuple have come to be occasionally used to refer to winning four, five or six top-tier trophies in a single season.
The list below considers only teams whose victories include trophies in the top tier of their league system.
Four titles in one season
Some clubs have won four competitions in a single season. This has sometimes been called a 'quadruple'.
Other teams have won four competitions in a calendar year, though not all in the same season.
Five titles in one season
Other teams have won five competitions in a calendar year, though not all in the same season. Liverpool achieved this in 2001, winning all competitions entered with the exception of the domestic league title; Internazionale achieved this feat in 2010 (no UEFA Super Cup), Spanish club F.C. Barcelona achieved this in 2011 (all but 2010–11 Copa del Rey) and 2015 (all but 2015 Supercopa de España); Germany's FC Bayern Munich won five trophies in 2013 (everything but the DFL-Supercup).
Six titles in a season
|Valletta||Malta||UEFA||2000–01||Maltese Premier League, Maltese Cup, MFA Super Cup, Löwenbräu Cup, Super 5 Lottery Tournament, Malta Centenary Cup|
|Arsenal Ladies||England||UEFA||2006–07||UEFA Women's Cup, FA Women's Premier League, FA Women's Cup, FA Women's Premier League Cup, FA Women's Community Shield, London FA Women's Cup|
The six titles won by Barcelona in 2009 (Copa del Rey, La Liga, UEFA Champions League, Supercopa de España, UEFA Super Cup and FIFA Club World Cup) have been described as a 'sextuple'. This achievement, however, took place over the course of two different Spanish seasons, including a treble in the 2008–09 season. Despite occurring in two seasons, the six titles are still counted as a 'sextuple' by many people, because the three added trophies (during the 2009–2010 season) were extra matches of the 2008–2009 treble and all six titles were won in the same calendar year.

- Similar to the requirement that a sextuple occur during the same season, golf requires that a "Grand Slam" (winning all four major championships) occur during the same season (which, in golf, coincides with the calendar year). Although Tiger Woods won all four majors in a row, he did so during two seasons. His achievement is known as the "Tiger Slam." Westin, David (March 24, 2012).
