Uropterygius inornatus is a moray eel found in the western Indian Ocean and in the Pacific Ocean to Hawaii.

Gosline in 1958, this eel typically resides in tropical marine environments and is reef-associated, often found in shallow lagoons or seaward reefs at depths of 8 to 18 meters.

The eel has a maximum length of about 19 cm and displays a uniform faded tan color, with the ventral side of the head and tail tip appearing paler.

Notably, it lacks vomerine teeth, which sets it apart from some related species.

As a benthic species, Uropterygius inornatus primarily inhabits crevices within reefs and is harmless to humans.
