Join Us is the fifteenth studio album from the rock band They Might Be Giants, released on July 19, 2011. It is the band's first adult album in four years since The Else in 2007. Following the success of their 2009 children's album, Here Comes Science, the band returned to their adult audience with Join Us, an eclectic collection of 18 songs.

In an interview with The A.V. Club, Flansburgh commented, "We probably recorded 30 songs for this album, and the songs that are on album are basically the last 15 or so. There were so many strange misfires at the beginning, just the most mutant songs." Some of the songs that were left off Join Us were later completed and released on the rarities compilation Album Raises New And Troubling Questions.
