We report the detection of optical pulsations at a period of 272.785+−0.003s from the newly discovered intermediate polar RX J0558.0+5353. This period nearly coincides with the X-ray period reported by Haberl et al. (1994). In the optical band the folded light curve of the star reveals a non-sinusoidal pulse with a pulsed fraction of 10.8%.
