V697 Sco, the remnant of Nova Scorpii 1941 and currently at V∼20.0, is found from photometric observations to have the characteristics of an intermediate polar with an orbital period (P orb ) of 4.49 hr and a rotation period (P rot ) of 3.31 hr. It therefore appears to be a member of the rare class of intermediate polars where P rot ∼P orb , which are probably diskless systems. The prominence of the modulation at 1 / 2 P rot , and its orbital sidebands, indicates two‐pole accretion.
