We consider regular surfaces $M$ that are given as the zeros of a polynomial function $p : \mathbb{R}^3 \rightarrow \mathbb{R}$, where the gradient of $p$ vanishes nowhere. We assume that $M$ has non-zero mean curvature and prove that there exist only two examples of such surfaces, namely the sphere and the circular cylinder
