The orbital period variation of the RS CVn-type binary system WW Dra was studied based on all available times of light minima. We confirmed that the orbital period of the binary shows a cyclical change with a large amplitude of 0.2495 days. We discussed in detail the mechanisms that could explain the period change of the system, especially the light-travel time orbit of a tertiary component or magnetic activity cycle. Of these two mechanisms, we find that the latter is more plausible.
