Guanlong is a genus of proceratosaurid dinosaur in the Jurassic World Evolution series. Originating from Late Jurassic Asia, this small crested theropod a more primitive relative of the larger Tyrannosaurus.

The name for this small tyrannosaurid dinosaur means "Crown Dragon", named for the large, air-filled cranial crest it possesses. This predator measures about 3 meters in length.

Preserved remains of a pair of Guanlong skeletons, one adult and one juvenile, were first discovered in the Wucaiwan area of Junggar Basin in China, buried in mudstone. A joint Chinese-American team discovered the dinosaur in 2002, and the Guanlong was first described to the scientific community in 2006.

Guanlong is one of the oldest-known of the tyrannosaurids, making it a distant ancestor of the famous Tyrannosaurus. However, Guanlong had a decorative crest that may have been used to attract mates. They lived in what is now northwestern China during the Late Jurassic period, about 160 million years ago, and were likely a secondary predator within its ecosystem, with a primitive carnosaur being the primary.
