Fun (often stylized as fun.) is an American indie pop band comprising of Nate Ruess, formerly of The Format, Andrew Dost (Anathallo) and Jack Antonoff (Steel Train). Over the course of seven years, fun. has released two albums: their debut Aim and Ignite in 2009 and their latest Some Nights in February, 2012.

Armed with anthemic, towering lyrics and electric vocals, fun. is among the most recent crop of indie-pop bands to cross into the mainstream. fun.’s success is attributed most majorly to the youthful “We Are Young” featuring Janelle Monáe. A smash on the Billboard Hot 100 after a memorable cover on Glee, the song is arguably fun.’s most defining track. Yet their discography has layers of depth past “Young” – the experimental “Stars,” the existential “Some Nights” (which also received significant commercial success), the nihilistic “Barlights,” the persevering “Carry On” – fun. is definitely a lyrically poignant and musically delectable group.

As of 2015, the group is on hiatus, with each member off working on solo projects. Lead singer Ruess released his solo debut, Grand Romantic, in June of the same year; guitarist Antonoff formed Bleachers and released Strange Desire in July 2014; Dost composed the soundtrack to the Jack-Black-led comedy, The D Train.
