Falcarius is a genus of therizinosaurian dinosaur found in the Cretaceous of east-central Utah, United States. Its name is derived from the word "sickle", falcarius in Latin being a sickle cutter, which scientists have used to describe its large clawed hands. Falcarius was a 4 metres (13 ft) long, bipedal herbivore. It had a small head and a long neck and tail.
