The White-rumped Falcon or White-rumped Pygmy-falcon (Polihierax insignis) is a species of bird of prey in the Falconidae family. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. It is sometimes placed in its own monotypic genus Neohierax.

Its natural habitats are subtropical or tropical dry forests and dry savanna. It is considered near-threatened by habitat loss due to logging and forest fires, and possibly hunting.
