We present the discovery of the photometric (orbital) period for V1974 Cygni (Nova Cygni 1992). The orbital period of 0.081263 +/- 0.000003 days places this classical nova just below the cataclysmic variable (CV) period gap. The modulation is driven by irradiation by the white dwarf (WD) heating one hemisphere of the red secondary and its aspect changes during orbital revolution.
