A vertex $w$ {\em strongly resolves} a pair $u, v$ of vertices of $G$ if there exists some shortest$u-w$ path containing $v$ or some shortest $v-w$ path containing $u$. A set $W$ of vertices is a {\em strong resolving set} for $G$ if every pair ofvertices of $G$ is strongly resolved by some vertex of $W$. The smallest cardinality of a strong resolving set for $G$ is called the {\em strong metric dimension} of $G$. It is known that the problem of computing the strong metricdimension of a graph is NP-hard. In this paper we obtain closed formulae for the strong metric dimension of several families of the Cartesian product of graphs and the direct product of graphs.
