In the title compound, C8H10O3, the hy-droxy-methyl group is twisted by 74.51 (13)° from the plane of the benzene ring to which it is connected. By contrast, the benzene and meth-oxy groups are almost coplanar, making a dihedral angle of 4.0 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
