The Double, in association football, is the achievement of winning a country's top tier division and its primary domestic 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 that holds the record for the most doubles is Linfield of Northern Ireland, with a total of 25.

South Africa and Trinidad and Tobago are the two countries with the most Double-winning clubs, with 13 clubs each.

In Albania, six teams have won the Double of the Kategoria Superiore and the Kupa e Shqipërisë.

In Armenia, four teams have won the Double of the Soviet Top League/Armenian Premier League and the Soviet Cup/Armenian Independence Cup.
