In the title compound, C16H15NO, there is a weak intramolecular C—H...O contact which leads to a planar acrylamide moiety. The phenyl ring forms an angle of 8.30 (2)° with the mean plane of the acrylamide moiety. The benzyl group is tilted against the cinnamamide unit, with the ring forming an angle of 77.11 (2)° with the cinnamamide unit mean plane. In the crystal, molecules are linked via N—H...O and C—H...O hydrogen bonds and C—H...π interactions, forming chains propagating along [001]. The chains are linked via further C—H...π interactions, forming layers parallel to the ac plane.
