We present the results of 11 nights of CCD photometry of V4743 Sgr (Nova Sagittarii 2002) from 2003 and 2005. Two periods of 6.7 hours and 24 min were identified in the 2005 data. The 2003 data also showed evidence of the longer period but only weak evidence of the shorter period. We suggest that the 6.7-hour periodicity represents the orbital period of the underlying binary system and that the 24-min period is the beat periodicity between the orbital period and the 22-min X-ray period, which is presumably the spin period of the white dwarf. Intermediate polars are a subset of the Am Her stars in which the spin period is much shorter than the orbital period, so we propose that V4743 Sgr is a member of this group.
