We construct the universal AdS$_{ 4}$ black hole that asymptotes to the $(\varphi,\chi)$-family of type IIB S-fold backgrounds dual to the conformal manifold of $\mathcal{ N}=2$ S-fold CFT's. We present the explicit type IIB embedding of such a universal black hole for two particular asymptotics: the $\,\mathcal{ N}=2\,$ S-fold with $\,\textrm{ U}(2)\,$ symmetry at $\,(\varphi,\chi)=(0,0)\,$ and the $\,\mathcal{ N}=4\,$ S-fold with $\,\textrm{ SO}(4)\,$ symmetry at $\,(\varphi,\chi)=(1,0)$. As a byproduct, we also present a novel $1/16$-BPS two-parameter family of $\,\textrm{ AdS}_{ 2} \times \textrm{ M}_{ 8}\,$ S-fold backgrounds with $\,\textrm{ M}_{ 8}=\mathbb{ H}^{ 2} \times \textrm{ S}^{ 5} \times \textrm{ S}^{ 1}$ that features a parametrically-controlled scale separation.
