'''Anapaite''' is a calcium–iron phosphate mineral with formula: Ca<sub>2</sub>Fe<sup>2+</sup>(PO<sub>4</sub>)<sub>2</sub>·4H<sub>2</sub>O. It is a mineral that typically occurs in cavities in fossil bearing sedimentary rocks. It is also found in phosphate bearing iron ores and rarely in pegmatites. It is commonly found with goethite, siderite and vivianite.<ref name=Mindat/>

It was named after the type locality on the Black Sea coastal region of Anapa, Taman Peninsula, Russia.<ref name=Mindat/> Noted localities include Kertch (Crimea, Ukraine), Bellver de Cerdanya (Lleida, Catalonia, Spain)<ref>{{Cite book |last=Calvo |first=Miguel |title=Minerales y Minas de España.
