40oz. to Freedom is the debut studio album by American ska punk band Sublime, released on June 1, 1992, on Skunk Records. It was later reissued by MCA. 40oz. to Freedom's sound blended various forms of Jamaican music, including ska ("Date Rape"), rocksteady ("54-46 That's My Number"), roots reggae ("Smoke Two Joints"), and dub ("Let's Go Get Stoned", "D.J.s") along with hardcore punk ("New Thrash", "Hope") and hip hop (as in "Live at E's").

40oz. to Freedom received mixed reviews from critics upon release, but has since earned an improved public perception. Sublime would not achieve any mainstream success until the release of their self-titled album in 1996, two months after the death of Bradley Nowell. As of 2011, the album has certified sales of two million copies in the US. It is Sublime's second bestselling studio album there; the self-titled album leads with six million. Along with the Offspring's album Smash, 40oz. to Freedom is one of the highest-selling independently released albums of all time.
