Ischnorhinidae is the second largest family of Cercopoidea, a xylem-feeding insect group, formerly included in the family Cercopidae, and similarly commonly called froghoppers.

They belong to the hemipteran suborder Auchenorrhyncha. A 2023 phylogenetic study of the superfamily indicated the elevation of the New World cercopid subfamily Ischnorhininae to full family status as Ischnorhinidae was necessary in order to create a monophyletic Cercopidae, thereby now restricted exclusively to the Old World. This was based on the closer phylogenetic ties of Ischnorhinidae to Machaerotidae than to the remaining Cercopidae. The Cercopidae senso stricto was then divided into two monophyletic subfamilies, Cercopinae and Cosmoscartinae, each with a number of tribes.
