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. Another method is to react yttrium carbide (YC₂) and elemental bromine. Yttrium(III) bromide can be reduced by yttrium metal to YBr or Y₂Br₃. It can react with osmium to produce Y₄Br₄Os.
