They Might Be Giants In... Holidayland (sometimes referred to simply as Holidayland) is a holiday-themed EP released by American alternative rock band They Might Be Giants in November 6, 2001 under Restless Records. The recording consists of: "Santa Claus", a Sonics cover; "Santa's Beard", first released on Lincoln and later '; "Feast of Lights" a song related to Hanukkah; "Careless Santa", from Mono Puff's album Unsupervised; and "O Tannenbaum" a song that was originally only limited addition.
All songs written by They Might Be Giants unless noted.
They Might Be Giants In... Holidayland received mixed reviews from critics. AllMusic gave it a 2 out of 5 stars stating that, "Unfortunately, the EP's newest track, a cover of the Sonics' 'Santa Claus,' is also the most unremarkable, but overall Holidayland will please the They Might Be Giants fans who don't already own these fun, festive songs."
