Microvenator (meaning "tiny hunter") is a genus of inosaur from the Early Cretaceous Cloverly Formation in what is now south central Montana. Microvenator was an Oviraptorosaurian theropod. Like other small theropods it probably had a carnivorous diet. The holotype fossil is an incomplete skeleton, most likely a juvenile, with a living length of about four feet. The adult size of Microvenator is estimated to be closer to 10 feet long.
