  Erd\H{o}s-Stone Theorem is a well-known result in extremal graph theory which
determines the asymptotic behaviour of maximum number of edges in an $n$-vertex
$H$-free graph. In 2009, Nikiforov gave a spectral version of Erd\H{o}s-Stone
Theorem. In this paper, we obtain a tensor's spectral version of
Erd\H{o}s-Stone Theorem.
