U.S. Route 160 (US 160), also known as the Navajo Trail, is a U.S. Highway which travels west to east across the Navajo Nation and Northeast Arizona for 159.35 miles (256.45 km). US 160 begins at a junction with US 89 north of Cameron and exits the state into New Mexico south of the Four Corners Monument. Along its journey, the route connects the communities of Tuba City, Moenkopi, Rare Metals, Tonalea, Tsegi, Kayenta, Dennehotso, Mexican Water, Red Mesa, and Teec Nos Pos.

Most of what is now US 160 was constructed as Navajo Route 1 between 1959 and 1962, and carried part of State Route 64 (SR 64) and the entirety of SR 364 between 1961 and 1965. From 1965 to 1970, the entire route of present day US 160 was designated as US 164, until US 160 was moved from its original alignment between Utah and Colorado, onto the entirety of US 164 between Arizona and Colorado.
