Molybdenum(III) bromide is the inorganic compound with the formula MoBr₃. It is a black solid that is insoluble in most solvents but dissolves in donor solvents such as pyridine.

Molybdenum(III) bromide is produced by the reaction of elemental molybdenum and bromine at 350 °C (662 °F).

It has a structure consisting of infinite chains of face-sharing octahedra with alternatingly short and long Mo-Mo contacts. The same structure is adopted by the tribromides of ruthenium and technetium. In contrast, in the high temperature phase of titanium(III) iodide, the Ti---Ti separation is invariant.
