State Route 84, also known as SR 84, is an east–west highway in south-central Arizona, with its western terminus at Exit 151 of Interstate 8 and its eastern terminus at its junction with State Route 387 and State Route 287 in Casa Grande.
The western terminus of Route 84 is located at exit 151 on I-8 in southern Arizona. From this interchange, it heads towards the northeast to an intersection with SR 347 which heads north to Maricopa. Route 84 continues towards the east from this intersection passing through Stanfield on its way to Casa Grande. The route reaches its eastern terminus at a junction with SR 287 and SR 387 in Casa Grande.
Until 1998, this route extended from its current westward terminus to Gila Bend and was known as the Gila Bend Highway. Although Interstate 8 serves as a replacement for much of its decommissioned length, the route still carries that name in Casa Grande. Route 84 formerly extended eastward as far as Tucson. The road surface is still maintained between Tucson and Eloy as a frontage road of Interstate 10 under various names. From its current eastern terminus, Arizona 84 previously extended southeast from Casa Grande with former State Route 93 through Eloy (Jimmie Kerr Boulevard / Frontier Street) to a junction with State Route 87, before joining the current route of Interstate 10.
This route serves as the only east–west thoroughfare in Stanfield, Arizona, but has been largely supplanted as a major road by Interstate 8.
The entire route is in Pinal County.
