35 Biggest Hits is a two-disc greatest hits album from American country music artist Toby Keith. It was released on May 6, 2008. 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. The album does not include any material from Big Dog Daddy.
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.
