Utahraptor (meaning Utah's predator) is a genus of large dromaeosaurid dinosaur that lived in North America during the Early Cretaceous period. It was a heavy-built, ground-dwelling, bipedal carnivore. It contains a single species, Utahraptor ostrommaysi, which is the largest-known member of the family Dromaeosauridae.

In 2018, it was proposed that Utahraptor be the Utah state dinosaur, an act that was approved by the Senate. Initially Utahraptor would have replaced another dinosaur, Allosaurus, as the state's official fossil, but it was decided that Utahraptor would be another symbol of the state.

Like other dromaeosaurids, Utahraptor had large curved claws on their second toes. The second pedal ungual is preserved at 22 cm (8.7 in) in length and is estimated to reach 24 cm (9.4 in) restored.

The largest described U. ostrommaysi specimen is estimated to have reached up to 7 m (23 ft) long and somewhat less than 500 kg (1,100 lb) in weight, comparable to a polar bear in weight. In 2012, the paleontologist Thomas R. Holtz Jr. estimated its weight around 230 to 450 kg (500 to 1,000 lb), comparable to a grizzly bear. However, the 2001 Kirkland discovery indicates the species may be far heavier than previously estimated. In 2016 Rubén Molina-Pérez and Asier Larramendi estimated the largest specimen at 4.65 m (15.3 ft) long, 1.5 m (4.9 ft) tall at the hips and 280 kg (620 lb) in weight.
