''XO'' is the name of the fourth album recorded by American singer-songwriter Elliott Smith. Smith's first work on a major label, it was released by DreamWorks Records on August 25, 1998. Bong Load Custom Records released it on vinyl LP, which has since gone out of print. Vinyl copies of ''XO'' remained rare until a re-release by Plain Records in 2008. The album is also available as digital download.

The singles from ''XO'' were "Waltz #2 (XO)" and "Baby Britain". An early working title for the album was ''Grand Mal''. Smith recorded numerous songs during the ''XO'' sessions that did not make it to the album.

Spin magazine included ''XO'' on their list of the best albums of the last 25 years, ranking it at #90. Writers at pitchfork.com placed the album at #23(original list) and #68(second edition) on their list of the best albums of the 90s.
