State Highway 78 or Texas 78 or SH 78 is a state highway that follows surface roads in a predominantly southwest-to-northeast direction in the Dallas before traveling 90 miles (145 km) north-northeast to the Oklahoma State border.

The highway's southern terminus is at Interstate 30 in Dallas. From there, it follows Grand Avenue along White Rock Lake and then Garland Road into Garland as it passes Interstate 635. In downtown Garland, Highway 78 follows the central streets of Avenues B and D before joining Lavon Drive and moving northeastward, where it forms the current eastern terminus of the President George Bush Turnpike.

It continues to the northeast through Sachse and Wylie, crossing between Lake Ray Hubbard and Lake Lavon. It passes through Lavon before turning north through Farmersville and Blue Ridge. At SH 160, just before SH 121, SH 78 turns east, continuing to Leonard before turning northeast again to Bailey. At Bailey, SH 78 turns north and cuts through Bonham (as Center Street) just before it reaches the border with Oklahoma, where it continues on as State Highway 78, which ends north of Durant, Oklahoma.

The highway was originally designated by 1933 along its current route. Part of this route was previously designated as SH 5C.
