Uranium(III) bromida adalah sebuah senyawa anorganik dengan rumus UBr₃. Senyawa ini bersifat radioaktif.

Pembuatan sunting

Uranium(III) bromida dapat diperoleh melalui reaksi antara logam uranium atau uranium(III) hidrida dan hidrogen bromida,^[1] atau dapat juga dibuat melalui dekomposisi termal NH₄UBr₄·1.5CH₃CN·6H₂O.^[2] Senyawa ini sulit untuk disintesis karena cepat teroksidasi di dalam air dan udara.^[3]
