Abstract: We consider the Liénard analytic differential systems $ \dot x = y$, $ \dot y= -cx -f(x)y$, with $ c \in \mathbb{R}$ and $ f: \mathbb{R}\to \mathbb{R}$ an analytic function. Then for such systems we characterize the existence of local analytic first integrals in a neighborhood of the singular point located at the origin.
