Yttrium(III) bromide is an inorganic compound with the chemical formula YBr₃. It is a white solid. Anhydrous yttrium(III) bromide can be produced by reacting yttrium oxide or yttrium(III) bromide hydrate and ammonium bromide. The reaction proceeds via the intermediate (NH₄)₃YBr₆.{{cite journal|author=Gerd Meyer, Siegfried Dötsch, Thomas Staffel|date=1987|title=The ammonium-bromide route to anhydrous rare earth bromides MBr3|journal=Journal of the Less Common Metals|language=en|volume=127|pages=155–160|doi=10.1016/0022-5088(87)90372-9}} Another method is to react yttrium carbide (YC₂) and elemental bromine.Mussler, R.
