#### Abstract

In characteristic $p = 0$ or $p \gt 5$, we show that a $\mathrm{K}3$ surface with an order 60 automorphism is unique up to isomorphism. As a consequence, we characterize the supersingular $\mathrm{K}3$ surface with Artin invariant $1$ in characteristic $p \equiv 11$ (mod $12$) by a cyclic symmetry of order 60.
