Pentamminechlororhodium dichloride is the inorganic compound with the formula [RhCl(NH₃)₅]Cl₂. This yellow solid is an intermediate in the purification of rhodium from its ores.

As shown by X-ray crystallography, the salt consists of the octahedral complex [RhCl(NH₃)₅]²⁺ and two chloride counterions. It forms from the reaction of rhodium trichloride and ammonia in ethanol. Two chloride anions are labile, whereas the coordinated chloride ligand is not.
