Mashrou’ Leila  is a Lebanese seven-member alternative rock band.
The band formed in Beirut, Lebanon in 2008 as a music workshop at the American University of Beirut. Led by frontman and co-founder Hamed Sinno, the band has released three studio albums, Mashrou' Leila (2008), El Hal Romancy (2011), an EP, and Raasük (2013) while causing many controversies due to their satirical lyrics and themes.

Mashrou' Leila's members enjoy the wordplay and ambiguity surrounding their band's name. In English, the name can be interpreted as either “One Night Project” or “Leila’s Project”; Leila being a very common given name in Lebanon.
When asked during an early interview about the origin of the name Mashrou' Leila, band members teasingly retorted that the band is a project started to collect money for a girl they knew called Leila. According to the band’s official Facebook page, Mashrou’ Leila means “An Overnight Project”, named for the nocturnal nature of the project characterized by all-night jam sessions.
