Kovdorskite, Mg2PO4(OH)·3H2O, is a rare, hydrated, magnesium phosphate mineral. It was first described by Kapustin et al.,[5] and is found only in the Kovdor Massif near Kovdor, Kola Peninsula, Russia.[6] It is associated with collinsite, magnesite, dolomite, hydrotalcite, apatite, magnetite, and forsterite.
