35 Biggest Hits is a two-disc greatest hits album from American country music artist Toby Keith.

[4] The album comprises thirty-four previously recorded tracks from Keith's previous studio albums, as well as the newly recorded track "She's a Hottie", which was released to radio in early 2008.

This compilation is the first to span Keith's entire career; it was able to do so because Universal Music Group Nashville owned (either outright or through distribution) the rights to his entire catalog.

The album has sold 1,210,900 copies in the United States as of January 2017.

[5] 35 Biggest Hits debuted at number two on the Billboard 200 albums chart, selling 103,000 copies in the first week of release.
