The TransAmerica Trail or TAT is a 4,253-mile (6,845 km) transcontinental vehicular route, intended as a recreational pathway across the United States using a minimum of paved roads, traveled by dual-sport motorcycles, off-road vehicle, or touring bicycle.

The trail was scouted by Sam Correro in 1984 who spent 12 years assembling the route using only publicly accessible roads and trails. To legally travel on the TAT, vehicles and drivers must be appropriately licensed for their type and class.
