L'hureaulite est un phosphate de manganèse rare, de formule chimique Mn₂⁺₅(PO₃OH)₂(PO₄)₂·4H₂O. Identifiée pour la première fois en 1825, elle fut nommée en 1826 d'après sa localité type, Les Hureaux, située à Saint-Sylvestre (Haute-Vienne, Limousin, France). Bien que l'orthographe « huréaulite » soit parfois employée, l'Association minéralogique internationale déconseille cette graphie dans les textes en anglais.
Une série minérale complète s'étend de la lithiophilite, LiMn2+PO4, à la triphylite, LiFe2+PO4, englobant l'hureaulite, la strengite, FePO4·2H2O, la stewartite, Mn2+Fe3+2(OH,PO4)2·8H2O, et la scklerite, (LiMn2+,Fe3+)PO4.
