State Highway 148, or SH 148, is a north–south state highway that runs from SH 79 in Petrolia, Texas through Henrietta, Texas to US 281 in Jacksboro, Texas.

Highway 148 is a two-lane improved surface highway that connects the various farming and economic centers of Clay and Jack County. Almost all of the route is rural and traffic is rarely a concern anywhere along the route. In Henrietta, the route parallels US Highway 82 approximately 1.4 miles (2.3 km) west and then splits north toward Petrolia.

SH 148 was originally designated by 1933 along a route from the Red River northwest of Petrolia to Henrietta. The route was extended to Jacksboro by 1939. The section north of Petrolia was transferred to FM 810 in 1948. In 1974, Highway 148 became nationally significant due to its appearance in the movie The Texas Chain Saw Massacre.
