A treble in association football is achieved when a club team wins three trophies in a single season. A continental treble involves winning the club's top-level domestic league competition, main domestic cup competition, and main continental trophy. Although winning a second-tier continental trophy has also been described as a continental treble, it is not as widely accepted. A domestic treble involves winning three national competitions—including the league title, the primary cup competition, and one secondary competition, such as a secondary cup or state-level league.

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.
