Dinosaur is a Statutory Town located in Moffat County, Colorado, United States. The town population is around 300. According to the United States Census Bureau, the town has a total area of 0.77 square miles (2.0 km2), all of it land.

Dinosaur has been noted for its unusual place name. The town of Dinosaur was originally named Artesia, and the current name was adopted in 1966. This quaint town became the gateway community to the archeologically and paleontologically rich Dinosaur National Monument, and renamed itself Dinosaur as a result.. The monument headquarters is located just east of the town on U.S. Highway 40.

Many streets in the town are named after dinosaurs, including Cletisaurus Circle, Tyrannosaurus Trail, and Antrodemus Alley.

The town is frequented by those returning from rafting adventures on the legendary Yampa and Green rivers, which flow through the monument well to the north. One of the many take-outs for these expeditions is in Echo Park, where the impressive Steamboat Rock rises over the confluence of the two rivers. This area remains a habitat for endangered peregrine falcons, golden eagles, bighorn sheep, Colorado pike minnows and razorback suckers. Those finishing their wilderness expeditions here can head into Dinosaur for much-needed rest and relaxation. Camping, hiking, hunting, fishing, mountain biking, four-wheeling and canoeing are also available in many of the public lands that surround the town. In fact, wildlife viewing in the area for deer, elk, antelope, fox and a variety of bird is sublime at dawn and dusk.
