State Route 79 (SR 79), also known as the Pinal Pioneer Parkway, is a state highway in the U.S. state of Arizona.

SR 79 has a northern terminus at U.S. Route 60 in unincorporated Florence Junction and passes through the town of Florence, its southern terminus is four miles (6 km) north of Catalina, at State Route 77, 25 miles (40 km) north of Tucson. The entirety of SR 79 is a direct surface route, roughly paralleling Interstate 10, (actually a north–south segment of the normally east–west freeway) and serving as the major route to Florence (which has no Interstate access), but the town of Florence is easily accessible from State Route 287, State Route 87, and Hunt Highway. It serves as the back-road to the Phoenix and Tucson Metropolitan Areas and control cities along this route show either Phoenix or Tucson.

The southern portion of SR 79 from Oracle Junction to just south of Florence is designated Pinal Pioneer Parkway, a scenic road of the high desert plain with views of the Santa Catalina and Tortoilla Mountains. The 41-mile stretch of road was so designated by the Arizona Highways Department in 1961.

Also along this road is a memorial marker for Tom Mix, who died after his Cord convertible crashed into what is now designated the Tom Mix Wash while bridge construction was incomplete. The single-car high-speed accident led to his death after leaving the Oracle Junction Inn in 1940.

SR 79 services the Florence Military Reservation which is a couple of miles north of Florence and the State, County, Private built or Federal Prisons in Florence.

It is a scenic and historic road between the metropolitan cities of Phoenix and Tucson if I-10 is closed due to an accident, weather or construction.

According to INRIX, a traffic-monitoring agency, as of 2011 Arizona State Route 79 was the fastest road in the nation, with the fastest 5% of the vehicles using it clocked at an average speed of 88 miles per hour.

SR 79 is the section of what was together U.S. Route 80 and U.S. Route 89 before both US routes were removed from southern Arizona in 1992.

The entire route is in Pinal County.

Business State Route 79 is a business loop in central Arizona. It lies entirely within the town limits of Florence located in Pinal County.

The road begins south of town at its parent State Route 79 near the Central Arizona Project canal and travels northbound on Main St passing a "Y" junction with State Route 287 to Coolidge. The road continues northbound to an intersection with Butte Ave, at a traffic light, where the highway turns east and passes the Pinal County Governmental Complex, it terminates at the junction with State Route 79 at the intersection of Butte Ave. and Pinal Parkway Avenue. It is the only state business loop in the state of Arizona. The junction with SR 287 and 79 is scheduled to be upgraded to a roundabout intersection. The current intersection has safety issues, including 8 driveways/entrance/exit points combining at different angles.

The business loop gives access to the historic downtown and business district in Florence, passing by the Pinal County Government Complex, Pinal County Historical Museum and 1891 Pinal County Courthouse.
