  For each del Pezzo surface $S$ with du Val singularities, we determine
whether it admits a $(-K_S)$-polar cylinder or not. If it allows one, then we
present an effective $\mathbb{Q}$-divisor $D$ that is $\mathbb{Q}$-linearly
equivalent to $-K_S$ and such that the open set $S\setminus\mathrm{Supp}(D)$ is
a cylinder. As a corollary, we classify all the del Pezzo surfaces with du Val
singularities that admit nontrivial $\mathbb{G}_a$-actions on their affine
cones defined by their anticanonical divisors.
