Below is a list and summary of the unconstructed state highways in the U.S. state of Arizona. Some are currently proposed while the others have been since cancelled prior to being constructed.

State Route 30 (formerly State Route 801), also known as the I-10 Reliever, is a planned state highway in the southwest parts of Phoenix, Arizona and nearby suburbs. It will connect the southern terminus of Loop 303 with the South Mountain leg of Loop 202. It is planned as a controlled-access freeway to relieve heavy traffic congestion experienced along Interstate 10 in the area.

State Route 50, also known as the Paradise Parkway, was a proposed urban freeway through Glendale and Phoenix. Originally proposed in 1968 as SR 317, the freeway would have run east to west, connecting the future State Route 51 and Loop 101, while running roughly parallel to, and 4 miles (6.4 km) north of, I-10 in the vicinity of Camelback Road. The proposed freeway was reassigned as SR 50 in 1987. As the proposed freeway would have crossed through largely developed land and densely populated neighborhoods, it proved to be both extremely expensive and highly unpopular. The route was eventually struck from state planning maps and all land acquired for right-of-way was subsequently sold, the funds being used to pay for other transportation projects.
