The concept of hop hub-integrity is introduced as a new measure of the stability of a graph $G$ and it is defined as $ H_hI(G) = min \{|S| + m(G - S)\},$ where $S$ is hop hub set and $ m(G - S)$ is the order of a maximum component of $(G - S)$. In this paper, the hop hub-integrity of some graphs is obtained.The relations between hop hub-integrity and other parameters are determined.
