No wave was an avant-garde music genre and visual art scene that emerged in the late 1970s in Downtown New York City. The term was a pun based on the rejection of commercial new wave music. Reacting against punk rock's recycling of rock and roll clichés, no wave musicians instead experimented with noise, dissonance, and atonality, as well as non-rock genres like free jazz, funk, and disco. The scene often reflected an abrasive, confrontational, and nihilistic world view.

The movement was short-lived but highly influential in the music world. The 1978 compilation No New York is often considered the quintessential testament to the scene's musical aesthetic. Aside from the music genre, the no wave movement also had a significant influence in independent film (no wave cinema), fashion, and visual art.
