Zoophthora is a genus of fungi in the family Entomophthoraceae. Like other taxa in this family, Zoophthora species cause disease in insects and as such are considered entomopathogenic fungi.

Like most entomopathogenic fungal taxa, Zoophthora has been studied largely in the context of biological control of insect pest species. However, recent research indicates that many fungal taxa that have historically been considered entomopathogenic (e.g., Zoophthora) may serve diverse ecological roles as free-living members of the rhizosphere, as endophytes of plant tissue, and as saprobes.
