A new period (P = 0 . d 5681643) for AX Draconis, based on all available times of minima, has been given. O-C diagrams for the star, based on various periods, have been given. A sinusoidal variation is apparent in figures, which is suggestive of the possible presence of a third body, having a period of more than 80 years.
