Berkelium(III) nitrate is the berkelium salt of nitric acid with the formula Bk(NO₃)₃. It commonly forms the tetrahydrate, Bk(NO₃)₃·4H₂O, which is a light green solid. If heated to 450 °C, it decomposes to berkelium(IV) oxide and 22 milligrams of the solution of this compound is reported to cost one million dollars.
