U.S. Route 80 or U.S. Highway 80 (US 80) is a major east–west United States Numbered Highway in the Southern United States, much of which was once part of the early auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the Pacific Ocean to the Atlantic Ocean. Its original western terminus was at Historic US 101 in San Diego, California. However, the entire segment west of Dallas, Texas, has been decommissioned in favor of various Interstate Highways and state highways. Currently, the highway's western terminus is at an interchange with Interstate 30 (I-30) on the Dallas–Mesquite, Texas city line. Its eastern terminus is in Tybee Island, Georgia near the Atlantic Ocean. Between Jonesville, Texas and Kewanee, Mississippi, US 80 runs parallel to or concurrently with Interstate 20. It also currently runs through Dallas, Texas; Shreveport, Louisiana; Jackson, Mississippi; Montgomery, Alabama; Columbus, Georgia; Macon, Georgia; and Savannah, Georgia.

Throughout its length west of Austin, US 290 cuts across mountainous hills comprising the Texas Hill Country and the Edwards Plateau; between Austin and Houston, the highway then travels through gradually hilly grasslands and pine forests comprising the Gulf Coastal Plains.
