State Highway Loop 288 is a state highway in the city of Denton, Texas. The southern portion of the loop has shopping centers, restaurants, and interchanges, while at the north side of the loop, it is rural and turns into a highway, with side streets, and one traffic light for Kings Row. It was constructed in 1955, and was finished in the 1970s. On the north side of town, the loop runs next to the C. H. Collins Athletic Complex. The road begins at an interchange with Interstate 35 (I-35) on the northwestern corner of Denton and loops around the north, east and southeast sides of the city before ending at another intersection with I-35E adjacent to Denton's shopping mall. Loop 288 is signed as a truck route for traffic traveling east on US Highway 380 (US 380) towards McKinney.

Loop 288 was designated on September 21, 1955, from US 77 north to US 380 (then State Highway 24, SH 24). Iit was designated to only bypass downtown. It was extended westward to I-35W and northward and westward to I-35 on June 9, 1966. On October 21, 1977, the section from I-35E to I-35W was canceled.

On May 29, 1991, another section of Loop 288 was proposed from Farm to Market Road 2181 (FM 2181) to another point on Loop 288. The south portion of the route, will become Spur 288 when the new route of Loop 288 is built. The proposed route would follow new construction from Spencer Road to Colorado Boulevard, Mayhill Road from Colorado Boulevard to I-35 and FM 2499, part of FM 2499 from I-35 to just south of Robinson Road, and new construction (right-of-way had already been acquired for this section) from just south of Robinson Road to FM 2181.

The entire route is in Denton, Denton County. All exits are unnumbered.
