U.S. Route 287 is a north–south United States highway. It is 1,791 miles (2,882 km) long. It serves as the major truck route between Fort Worth, Texas and Amarillo, Texas, and between Fort Collins, Colorado and Laramie, Wyoming. The highway is broken into two segments by Yellowstone National Park, where an unnumbered park road serves as a connector.

The highway's northern terminus is in Choteau, Montana, 100 miles (161 km) south of the Canadian border, at an intersection with U.S. Route 89. Its southern terminus (as well as those of US 69 and US 96) is in Port Arthur, Texas at an intersection with State Highway 87, five miles (8 km) up the Sabine River from the Gulf of Mexico. It intersects its parent route U.S. Route 87 twice, overlapping it from Amarillo, Texas to Dumas, Texas, and then crossing it in Denver, Colorado.

US 287 is the shortest route between Denver and Dallas-Fort Worth.
