The title compound, C5H7BrO2, crystallized in space group P. Molecules are linked to form normal centrosymmetric hydrogen-bonded dimers with OO 2.625 (4) Å. The carboxyl H and O atoms are ordered, but the H atoms of both methyl groups are disordered. The Br and C atoms lie very nearly in a plane which makes a dihedral angle of 30.0 (1)° with the carboxyl group plain.
