Lanthanum(III) bromide (LaBr₃) is an inorganic halide salt of lanthanum. When pure, it is a colorless white powder. The single crystals of LaBr₃ are hexagonal crystals with melting point of 783 °C. It is highly hygroscopic and water-soluble. The salt forms several hydrates with general formula LaBr₃·xH₂O. It is often used as a source of lanthanum in chemical synthesis and as a scintillation material in certain applications.
