The Double, in association football, is the achievement of winning a country's top tier division and its primary cup competition in the same season. The lists in this article examine this definition of a double, while derivative sections examine much less frequent, continental instances. The Double can also mean beating a team both home and away in the same league season, a feat often noted as doing the double over a particular opponent.
The first club to achieve a double was Preston North End in 1889, winning the FA Cup and The Football League in the inaugural season of the league.
The team who holds the record for the most doubles is Linfield of Northern Ireland, with a total of 23.
In Afghanistan, there are no national cups. The Afghan Premier League is the only national football competition in the country since 2012.
From 1977 to 1997, the double could be achieved in Australia by winning the National Soccer League and the NSL Cup.
Between 1997 and 2014, Australia had no national cup competition so the traditional league and cup double could not be achieved. Since the formation of the A-League in 2004, a double could be accomplished by winning the Premiership in the regular league season and the Championship in the finals series. The feat of winning the minor premiership and the finals during the NSL era was not officially recognised as a 'double'.
From 2014–15, the FFA Cup will take place on an annual basis.
In Bahrain three teams have won the Double of the Bahraini Premier League and the Bahraini King's Cup.
