Grimborg is the third studio album by the Finnish folk/world music group Gjallarhorn, released in 2003.

The Allmusic review by Chris Nickson awards the album 4.5 stars and states "There's nothing like the pleasure one can get from hearing a band take a quantum leap in its development, and with the very purplish Grimborg (just look at the cover), Gjallarhorn has made theirs.
