We present a period analysis of the near-contact binary CN And using all available times of light minima. It is revealed that the orbital period exhibits a long-term decrease as well as a small-amplitude cyclic oscillation. This result suggests that the secular period decrease at the rate of dP/dt = -1.4017 x 10^–7 d yr^–1 is caused by a combination of mass transfer and angular momentum loss due to magnetic braking. The periodic variation with an amplitude of A = 0.0036 d and a period of P_mod = 28.3542 yr should be rooted in the light-time effect of a third body, rather than cyclic magnetic activity.
