State Highway 360 or SH 360 is a 28.00-mile (45.06 km) north–south state highway in the Dallas–Fort Worth Metroplex in the U.S. state of Texas.

The freeway was constructed in different stages over the course of several decades. For the most part, each section's frontage roads were built first, handling all of the traffic years before the actual freeway portion was completed (or even begun). Similarly, the interchanges at Interstate 20, Interstate 30, and Highway 183 were in place long before the freeway lanes were completed.

The interchange at Interstate 30 is a holdover from when that freeway was a toll road (see Dallas-Fort Worth Turnpike). The design was such that any traffic moving from one freeway to the other was routed through one common, bi-directional ramp. This was a cost-saving measure as it required fewer toll booths. However, this remains a major bottleneck, compounded by the fact that it intersects with surface streets, and is near a major tourist attraction, Six Flags Over Texas.

SH 360 has its northern terminus at State Highway 121 in Grapevine as a freeway. It follows the western boundary of the Dallas/Fort Worth International Airport to its interchange with State Highway 183 near Euless, and then takes a nearly north–south course through Arlington roughly on its boundary with Grand Prairie, with complicated access to Interstate 30, the former Dallas-Fort Worth Turnpike, and an interchange with Interstate 20 on the south side of Arlington. The original alignment south of Highway 183 was called Watson Road.

The segment through Arlington is officially designated as the "Angus G. Wynne Freeway" (after the founder of Six Flags); however, neither the official designation nor the older Watson Road name are locally used, the road is generally called "360".

Around two miles south of I-20, the freeway ends at an intersection with Sublett Road/Camp Wisdom Road. SH 360 then continues south as a pair of frontage roads about seven miles to the Tarrant-Ellis county line. From there it runs another two miles as a two-lane highway to its southern terminus at US 287 near the Ellis-Johnson county line.

On January 25, 2013, North Texas Tollway Authority approved a deal to develop the 10-mile unfinished portion of the highway from Camp Wisdom Road/ Sublett Road in Arlington/ Grand Prairie to U.S. 287 in Mansfield into a toll road, in a partnership with the Texas Department of Transportation which is expected to cost $600 million. The road would be expanded to four main lanes all the way to Broad Street and two main lanes from Broad Street to U.S. 287. Frontage road improvements are also planned.
