A new cataclysmic variable is identified as the optical counterpart of the X-ray source RX J0757.0+6306. The emission lines bear evidence of a strong disc with an S-wave with period of 75±1.4 min, which we identify with the orbital period of the system. CCD photometry reveals an additional period of 8.45 min. which is stable over five nights. We assume it is the spin period of the accreting primary. We tentatively identify RX J0757.0+6306 as an intermediate polar.
