State Highway 205 (SH 205) is a Texas state highway that runs from US 80/FM 148 in Terrell, traveling through Rockwall before ending at SH 78 in Lavon.

SH 205 begins at a junction with US 80 and FM 148 in Terrell. It heads northwest from this junction to an intersection with FM 1392. The highway continues to the northwest to an intersection with FM 548. Heading towards the northwest, the highway continues to a junction with FM 550 in McLendon-Chisholm. The highway continues to the northwest to an intersection with FM 549 in Rockwall. It continues to the northwest through Rockwall to a junction with SH 276. As the highway continues to the northwest through Rockwall, it intersects I-30. It turns towards the north from this junction to an intersection with FM 740. The highway continues to the north through Rockwall along Goliad Street. Near the town square, SH 205 runs along a pair of one-way streets with northbound traffic traveling on Goliad Street and southbound on Alamo Road, intersecting SH 66 in downtown. Leaving the downtown Rockwall area, the highway becomes a two-way road again. Heading towards the north, the highway continues to a junction with FM 552 before leaving Rockwall. SH 205 reaches its northern terminus at SH 78 in Lavon.

This route was designated on May 15, 1934, from Terrell to Rockwall,^[2] and was extended north to Lavon on September 1, 1939.^[3] The route has been under heavy construction since 2006 as part of a new expansion and widening project, and was scheduled to be completed in 2011.

The highway has a bypass road as well, John King Boulevard, that bypasses Rockwall, running a few miles east of SH 205. Planning for a bypass around Rockwall began in the early 2000s and opened to traffic on August 3, 2012.^[4]
