The Entomophthorales are an order of fungi that were previously classified in the class Zygomycetes. A new subdivision, Entomophthoromycotina, in 2007, was circumscribed for them.

Most species of the entomophthorales are pathogens of insects. A few attack nematodes, mites, and tardigrades, and some (particularly species of the genus Conidiobolus) are free-living saprotrophs.

The name "entomophthorales" is derived from the Ancient Greek for insect destroyer (entomo- = referring to insects, and phthor = "destruction"). Named after genus Entomophthora in 1856.
