The status σ (*u*) of a vertex *u* is defined as the sum of the distances between *u* and all other vertices of a graph *G*. In this paper we have defined the harmonic status index of a graph *G* as and obtained the bounds for *HS*(*G*). Further the harmonic status index of some graphs is obtained.
