In theatres, beginning in Elizabethan London, a jig was a short comic drama that immediately followed a full-length play. This phenomenon added an additional comic or light-hearted offering at the end of a performance. A jig might include songs sung to popular tunes of the day, and it might feature dance, stage fighting, cross-dressing, disguisings, asides, masks, and elements of pantomime.

The jig is a form of lively folk dance in compound metre, as well as the accompanying dance tune. It first gained popularity in 16th-century England, Ireland, Scotland, and other parts of the British Isles, and was adopted on mainland Europe where it eventually became the final movement of the mature Baroque dance suite. Today it is most associated with Irish dance music, Scottish country dance and the Métis people in Canada. Jigs were originally in quadruple compound metre,, but have been adapted to a variety of time signatures, by which they are often classified into groups, including double jigs, slip jigs and single jigs.
