Rhodium(III) nitrate is a inorganic compound, a salt of rhodium and nitric acid with the formula Rh(NO₃)₃. This anhydrous complex has been the subject of theoretical analysis but has not been isolated. However, a dihydrate and an aqueous solution are known with similar stoichiometry; they contain various hexacoordinated rhodium(III) aqua and nitrate complexes. A number of other rhodium nitrates have been characterized by X-ray crystallography: Rb₄[trans-[Rh(H₂O)₂(NO₃)₄][Rh(NO₃)₆]{{cite journal|journal=European Journal of Inorganic Chemistry|page=3822 - 3828|year=2016
