‎‎We introduce the notion of an $m$-convex set-valued‎ ‎function and study some properties of this class of functions‎. ‎Several characterizations are given as well as certain algebraic‎ ‎properties and examples‎. ‎Finally‎, ‎an inclusion of Jensen type is‎ ‎presented jointly with a sandwich type theorem‎.
