Abstrakt:	The title compound, C10H8BrNO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and the conformation across the C=N bond is trans. Further, the O atom of the benzo-furan ring is syn to the N atom of the oxime group. In the crystal, inversion dimers linked by pairs of O-H⋯N hydrogen bonds generate R 2 (2)(6) loops. Very weak aromatic π-π stacking inter-actions [centroid-centroid separations = 3.9100 (12) and 3.9447 (12) Å] are also observed.
