In the title compound, C15H11BrO3, the dihedral angle between the naphthofuran ring system (r.m.s. deviation = 0.022 Å) and the side chain is 4.50 (2)°. In the crystal, short BrBr [3.4435 (7) Å] contacts propagating along  in a zigzag manner and weak - interactions [shortest centroid-centroid separation = 3.573 (2) Å] directedalong  are observed.
