Saurornitholestes ("lizard-bird-robber") is a genus of small theropod dinosaur from the Upper Cretaceous of North America.

Some incomplete skeletons and many individual bones and teeth were found in Dinosaur Provincial Park in the Canadian province of Alberta and are on display at the Royal Tyrrell Museum of Palaeontology . Judging by the number of finds, it appears to have been the most common Dromaeosauridae . The fossils are dated to the late Campanian and are thus around 76 to 72 million years old.

As with other theropods from the Dromaeosauridae family, the second toe of the Saurornitholestes' foot was designed as a large sickle claw. Saurornitholestes had a long neck, was about the size of a coyote, and probably closely related to Velociraptor .

A Saurornitholestes tooth was found in a wing bone of the giant pterosaur Quetzalcoatlus . It is not known whether he actually killed the much larger animal or ate carcass from a carcass.
