In this paper, we consider some piecewise smooth Liénard systems and study the Hopf bifurcation of limit cycles from the origin after a perturbation. We define the cyclicity [Formula: see text] of the piecewise smooth Liénard systems at the origin and denote [Formula: see text] for fixing [Formula: see text]. Then we obtain [Formula: see text] [Formula: see text]; [Formula: see text] [Formula: see text] and [Formula: see text] [Formula: see text].
