Gadolinit adalah sebuah mineral silikat yang kebanyakan mengandung silikat-silikat serium, lantanum, neodimium, itrium, berilium, dan besi dengan formula (Ce,La,Nd,Y)2FeBe2Si2O10. Mineral tersebut disebut gadolinit-(Ce) atau gadolinit-(Y), tergantung pada unsur penyusunnya yang menonjol (Y jika itrium mendominasi, dan Ce jika cerium). Mineral tersebut mungkin mengandung 35,5% sub-kelompok tanah jarang itria, 2,2% seria tanah, sebanyak 11,6% BeO, dan torium. Mineral tersebut ditemukan di Swedia, Norwegia, dan AS (Texas dan Colorado).
