They Might Be Giants In... Holidayland (sometimes referred to simply as Holidayland) is a holiday-themed EP released by American rock band They Might Be Giants in 2001 under Restless Records. The recording consists of: "Santa Claus", a Sonics cover originally released on Emusic.com's TMBG Unlimited service; "Santa's Beard", first released on Lincoln and later Then: The Earlier Years; "Feast of Lights", also from TMBG Unlimited, and appearing on the compilation Festival of Lights 2; "Careless Santa", from Mono Puff's album Unsupervised; and "O Tannenbaum", from 1993's O Tannenbaum EP and, later, TMBG Unlimited.
The EP itself is not a complete collection of holiday songs by the band, leaving out "Christmas Cards" (the original B-side of "O Tannenbaum") and the Dial-A-Song exclusive "We Just Go Nuts At Christmas Time."
