Luk (stylised as Lюk) was a Ukrainian music band from Kharkiv. The band's style joins acid jazz, lounge and rock. In their texts musicians used mostly Ukrainian, Russian and French.

Luk was formed in 1999. The name was given accidentally without special meaning (люк means manhole). After released four studio albums Luk declared its break up in 2011.

Luk collaborated with Kharkiv-based Ukrainian writer Serhiy Zhadan. Most of their Ukrainian-language songs were written in lyrics of Zhadan (in particular the first album Tourist zone is based on Zhadan's play "Merry Christmas, Jesus Christ"). Also Luk recorded a lot of songs with 5'Nizza member Andriy Zaporozhets (in particular the second album is a result of collaboration with Zaporozhets). Their third album contains two songs recorded with other 5'Nizza musician Serhiy Babkin.
