Abstract: The purpose of this paper is to show that if $X$ is a completely regular ${T_1}$-space, then $\mathcal {C}(X)$, the space of all compact subsets of $X$ with the Vietoris topology, is realcompact (topologically complete in the sense of Dieudonné) if and only if $X$ is realcompact (topologically complete in the sense of Dieudonné).
