Electroclash is a style of music that fuses New Wave synthpop and electronic dance music. It emerged in New York and Detroit in the later 1990s, pioneered by acts including I-F and those associated with Gerald Donald, and is associated with acts including Peaches, Adult, and Fischerspooner. It was popularised by the Electroclash Festival in 2001 and 2002 and subsequent European tours, but faded as a distinctive style in the early 2000s.

The term electroclash was coined by New York DJ and promoter Larry Tee to describe music that combined synthpop, techno, punk and performance art. The genre was a reaction to the rigid formulations of techno music, putting an emphasis on song writing, showmanship and a sense of humour, described by The Guardian as one of "the two most significant upheavals in recent dance music history". The visual aesthetic of electroclash has been associated with the 1982 cult film Liquid Sky.

Electroclash emerged in New York at the end of the 1990s. It was pioneered by I-F with their track "Space Invaders Are Smoking Grass" (1998), and Collider with their 1998 album Blowing Shit Up (though Collider called its own style "electropunk" as the genre had not yet been named). The style was pursued by artists including Felix da Housecat,Peaches and Chicks on Speed. During the early years, Ladytron were sometimes labeled as electroclash, but they rejected this tag.Goldfrapp's albums Black Cherry (2003) and Supernature (2005) incorporated electroclash influences.
