Umohoite is a rare oxide and hydroxide mineral. The name of this mineral reflects its composition: uranyl (U), molybdate (Mo) and water (H2O). Its chemical formula is (UO2)MoO4·2H2O.[3]

Umohoite's type location is in Marysvale, the mineral was first described by Paul F. Kerr and G. P. Brophy in 1953.[4]
