RE 0751 + 14 shows an 833-s spin pulsation which is quasi-sinusoidal in the blue, but double-peaked in the red. We present the first ephemeris for this pulsation. A weaker 872-s pulsation is also double-peaked, and is probably caused by reprocessing of the double-peaked X-ray pulse. The optical modulation at the implied orbital period is weaker than in any other intermediate polar, which suggests that RE 0751 + 14 is at a low inclination.
