Ovoo gurvel /ˈoʊvoʊ/ is an extinct varanid lizard from the Late Cretaceous of Mongolia.

The generic name is derived from the name of a type of cairn called ovoos that are found along roads near Little Ukhaa.

Features linking it with these lizards include a rounded snout and a lack of contact between the maxillae and frontal bones.

Because of their age, Ovoo, Aiolosaurus, and Cherminotus may be representatives of the first radiation of monitor lizards.
