State Route 80 (SR 80) is a 120.20-mile (193.44-kilometre) long, roughly arc-shaped highway lying in southeastern Arizona. Starting in downtown Benson, the highway serves as the main route through the towns of St. David, Tombstone, Bisbee and Douglas before terminating at the New Mexico state line, becoming New Mexico State Road 80 (NM 80). SR 80 also acts as the national southern terminus of US 191 near Douglas and provides the only connection between the U.S. Highway and its business route in Douglas.

Both SR 80 and NM 80 were once part of U.S. Route 80, which traveled through Arizona between San Diego, California and Savannah, Georgia, starting in 1926. The US 80 designation was retired from this route in 1989 after being made redundant by Interstate 10. Despite being replaced by the Interstate, this segment of old US 80 was not closely paralleled by or reconstructed into I-10, as the Interstate was constructed further north and instead supplants the shorter former route of SR 86 and NM 14.
