State Highway 178 or SH 178 is a Texas state highway in the city of El Paso in El Paso County maintained by the Texas Department of Transportation (TxDOT). The 3.0-mile (4.8 km) route designated in 1991 connects New Mexico State Road 136 at the New Mexico state line between El Paso and Santa Teresa, NM to a freeway carrying Interstate 10, U.S. Route 85, and U.S. Route 180 on the west side of El Paso. The route together with NM 136 is a major urban roadway connecting an international border crossing with I-10. The route also has an important intersection with SH 20.

The route's numerical designation was previously assigned to a road in the Texas Panhandle during the 1930s. An extension to the current route potentially doubling its length was considered and rejected in recent years.

SH 178 was previously proposed by 1933 as a connector route between the cities of Hartley and Dumas in Hartley and Moore counties in the Texas Panhandle. By 1936, the Hartley County portion had been completed with the Moore County portion following by 1940. The route had been reassigned as US 87 during the 1939 general redescription of the state highway system.
