'''Xenotime-(Gd)''' is a [[Xenotime]] species with the ideal formula {{chem2|Gd(PO4)}}, being one of the few known [[gadolinium]]-dominant [[rare earth mineral]]s.

Xenotime deposits rich in [[gadolinium]] were reported in 2023 from the [[Slovak Ore Mountains]] along with other [[rare earth minerals]] enriched in elements classified as medium rare earth elements (MREE).<ref name=Ondrejka2023>{{cite journal |vauthors=Ondrejka M, Uher P, Ferenc S, Milovska S, Mikus T, Molnarova A, Skoda R, Kopacik R, Bacik P
