In the title compound, C(11)H(9)NO(2), the mean planes formed by the phenyl and acryl group are almost orthogonal to each other, with a dihedral angle of 88.61 (7)°. The carbonitrile side chain is almost linear, the C-C-N angle being 179.54 (16)°. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O inter-actions into infinite chains running parallel to the b axis.
