We examine the holographic entanglement entropy in hyperscaling violating backgrounds. Pre-
cisely in such theories by semi-analytic computation, we use holographic methods to derive the
universal terms of entanglement entropy in various dimensions. We also find such terms when the
bulk action includes higher-order curvature terms. We make further comments on the mutual infor-
mation in hyperscaling violating backgrounds with higher curvature interactions. We explore the sign
of tripartite information which results in a monogamy property on mutual information. It is shown
that for various hyperscaling parameters, the mutual and tripartite information are always positive
and negative, respectively. This indicates that mutual information is monogamous in theories with
hyperscaling violation.
