The title compound, C17H12O, has an E conformation about the C=C bond. The C-CC-C torsion angle is 7.7 (2)°, and the mean planes of the phenylethylenone [r.m.s. deviation = 0.059 (1) Å] and phenylacetylene [r.m.s. deviation = 0.023 (1) Å] fragments form a dihedral angle of 14.16 (7)°. In the crystal, weak C-HO interactions link the molecules into zigzag chains propagated in .
