State Route 88 (SR 88) is a 45.67 mi (73.50 km) long state highway in the U.S. state of Arizona. It runs from U.S. Route 60 (US 60) in Apache Junction through desert terrain to SR 188 near Roosevelt Dam. Following the Salt River for much of its length, the section east of Tortilla Flat is known as the Apache Trail and is part of the National Forest Scenic Byway system. The Apache Trail was built in the mid-1920s and the number 88 was assigned in 1927. An eastern extension of SR 88 to Globe was redesignated as SR 188 in the late 1990s.

SR 88 begins at a diamond interchange with US 60, the Superstition Freeway, in southern Apache Junction. The route follows Idaho Road northward through a residential area with four lanes. Following a junction with Old West Highway, SR 88 turns northeast onto Apache Trail and narrows to two lanes. The route exits the city limits of Apache Junction, entering desert terrain. Passing a ghost town known as Goldfield, Apache Trail enters Tonto National Forest just northwest of Lost Dutchman State Park. SR 88 nears Canyon Lake south of the Mormon Flat Dam and follows a part of the southern coast of Canyon Lake. Apache Trail heads away from the Salt River. It passes through the town of Tortilla Flat, becoming an unpaved dirt trail winding eastward through the Superstition Mountains. SR 88 again turns northeast and nears Apache Lake. The route follows the Salt River northeast to the Theodore Roosevelt Dam, near which the route is again paved. SR 88 intersects with SR 188 along the coast of Theodore Roosevelt Lake.
