Boksit utawa bauksit, iku wiji alumunium sing paling wigati. Dat iki dumadi akèh-akèhé saka bahan logam gibbsite Al(OH)3, boehmite γ-AlO(OH), lan alumunium dioksida hidroksida (diaspore) α-AlO(OH), bebarengan karo oksida wesi goethite lan hematite, lempung mineral kaolinite lan sethithik anatase TiO2. Dat iki dijenengaké saka jeneng désa Les Baux ing Prancis kidul, papan tinemu sepisanan dat iki ing taun 1821 déning geologis Pierre Berthier.
