Gadolinium(III) bromide is a crystalline compound of gadolinium atoms and three bromine atoms. This salt is hygroscopic.

Gadolinium(III) bromide can be obtained by the reaction between gadolinium and hydrobromic acid: ^[3]

${\displaystyle \mathrm {2\ Gd+6\ HBr\longrightarrow 2\ GdBr_{3}+3\ H_{2}} }$

The anhydrous form can be obtained by heating the hydrate with ammonium bromide. ^[3]
