Elephants... Teeth Sinking Into Heart is the second full-length album by Rachael Yamagata. It was released on 7 October 2008 via Warner Bros. Records in North America. (International release dates are yet to be announced.)

The album is split into two CDs: Elephants, featuring a darker, more vulnerable and intimate tone, which is said to be more familiar with Yamagata's debut, Happenstance; while Teeth Sinking Into Heart, shows a grittier, more cynical side of the artist, who has described it as "this mix of 'Pulp Fiction' surf guitar, PJ Harvey [and] Tom Waits-flavored rock tunes which would be great to play live but ... just developed into this entity that would break the beauty of ('Elephants')." The album contains fifteen tracks (one of them hidden), ten appearing in the first disc, Elephants, and five in Teeth Sinking Into Heart.

Most of the album was produced by Mike Mogis, known for previous works with artists such as Bright Eyes, Rilo Kiley, and The Faint, among others. John Alagia, who produced Yamagata's first album, Happenstance, has also produced two of the tracks in this record ("What If I Leave", and "Horizon").

The release of this album comes over four years after Yamagata's debut; this delay was caused by changes at her original label, RCA, which ultimately led her to be released from her contract there. She has also changed managers during that time.
