State Highway 11, or SH 11, is a highway that runs from US 59 in Linden to SH 56 in Sherman in northeast Texas.

SH 11 begins at an intersection with State Highway 56 on the easternedge of Sherman, just north of the Sherman Regional Airport. The route then travels to the southeast through Northeast Texas. In 2009, it was rerouted around the city of Commerce, concurrent with State Highway 24 and State Loop 178, with the old routing through Commerce transferred to a business route. It continues southeast toward Sulphur Springs, where it shares a concurrency with State Highway 154 and the old routing of US 67, and intersects I-30 on the south side of town. After Sulphur Springs, the route takes a more easterly direction through Northeast Texas, before reaching its eastern terminus at US 59 on the eastern edge of Linden.

State Highway 11 was one of the original twenty-six state highways proposed in 1917, overlaid on top of the 'Jefferson Highway.' In 1917 the routing was proposed from the Oklahoma border at Denison, south on present day U.S. Highway 69 through Whitewright into Greenville. From Greenville, it went east on U.S. Highway 67 to Mount Pleasant, and south on U.S. Highway 271 to Gilmer and along State Highway 300 to Longview, and finally, U.S. Highway 80 through Marshall to the Louisiana border.

In 1919 the segment from Gilmer to Longview had yet to be built, so the road was rerouted over the current US 271 and US 80 routes through Gladewater, Texas.

In 1926 US 67, 271 and 80 were overlaid onto segments of SH 11. While the routes were marked concurrently, by 1933, SH 11 had lost all of its original assignment and had been reassigned to nearby towns the U.S. highways had not reached. The road now began in Ladonia and via the present day State Highway 50 to Commerce where it followed the current SH 11 from to Daingerfield, then north on U.S. Highway 259 through Omaha and terminating in De Kalb

By 1939 the US 259 segment of SH 11 was cancelled, and SH 11 was extended from Daingerfield to Linden via its current alignment, replacing SH 47, and up US 59 to a terminus in Texarkana. The US 59 alignment of SH 11 was removed in 1947, The Ladonia-Commerce segment was removed and replaced with its current assignment in 1971 over what was previously designated as State Highway 314.
