Our CCD V band photometry of the classical nova V2468 Cygni taken in 2012, 4.5 years after its outburst, revealed the strictly periodic brightness variations with the amplitude of 0.09 mag and period of 0d.145250(5),which we interpret as the orbital period of the binary. Till the increase of X-ray brightness in July 2012 the orbital light curve was largely influenced by a presence of 21-50 minutes quasi-periodic oscillations with amplitudes up to 0.9 mag.
