State Highway 276 (SH 276) is a Texas state highway that runs from Rockwall east to Emory. This route was designated on July 25, 1960, between Rockwall and Quinlan, replacing FM 1143 and part of FM 35. SH 276 was extended to its current terminus on October 25, 1990, replacing most of FM 35.
SH 276 was first designated on September 7, 1938, as a route between US 285 southeast of Arno and Mentone.[1] On April 16, 1946, another section from SH 115 to what was then SH 82 (now SH 18) in Kermit was added. On August 12, 1946, that section was transferred to SH 302. On December 1, 1953, the original SH 276 was canceled and the mileage was transferred to SH 302.
The current SH 276 was designated in 1960, running from SH 205 near Rockwall east to SH 34 in Quinlan. In 1990, the route was extended east to US 69 in Emory, with SH 276 absorbing the easternmost part of FM 35 in the process.
In early 2021, construction began near Quinlan to eliminate the SH 276/SH 34 concurrency by rerouting SH 276 along the south side of Quinlan from its intersection with SH 34 and reconnecting with the existing SH 276 west of the city.[2] On February 27, 2023, the new route of 276 was officially opened, while the existing 276 that ran from FM 36 to Downtown Quinlan was shut down to be reconstructed into Bus. SH 276-D.[3] On April 29, 2023, the intersection of SH 276 and Bus. SH 276-D was opened up to traffic.

SH 276 officially has one business route, Business State Highway 276-D (Bus. SH 276-D), located in Quinlan. The business route was designated on April 29, 2023 when SH 276 was rerouted south of Quinlan. The highway is known locally as Main Street and travels along a former routing of its parent highway. Bus. SH 276-D begins at an intersection with SH 276 just west of Quinlan. The highway travels east along Main Street and intersects Spur 264 (an old routing of SH 34) a few blocks west of the town square. Leaving the town square, the highway continues to travel eastward along Main Street before ending at an intersection with SH 34.
