Fluorwavellite is a rare[2] phosphate mineral with formula Al3(PO4)2(OH)2F•5H2O.[3] As suggested by its name, it is a fluorine-analogue of wavellite (hence its name), a rather common phosphate mineral. Chemically similar aluminium fluoride phosphate minerals include fluellite, kingite and mitryaevaite.[4][5][6]
