U.S. Route 285 is a north–south United States highway, running 846 miles (1,362 km) through the states of Texas, New Mexico and Colorado. The highway's southern terminus is in Sanderson, Texas at an intersection with U.S. Route 90. US 285 has always had an endpoint in Denver, Colorado, although the original US 285 went north from Denver (that segment is now a part of U.S. Route 287). Today the highway's northern terminus is in Denver, at exit 201 on Interstate 25.

US 285 is a secondary route of US 85, which it crosses in metro Denver, and technically crosses again in Santa Fe, New Mexico (today its parent route is largely concurrent with Interstate 25 through New Mexico, and as a result US 85 is no longer signed in New Mexico). US 285 also intersects a sibling route, US 385, in Fort Stockton, Texas.
