State Highway 82 or SH 82 is a state highway in the U.S. state of Texas that runs 13 miles (21 km) from the Louisiana border as a continuation of Louisiana Highway 82 to Port Arthur. This route was designated in 1975.

SH 82 was originally designated in 1926 on a route from the New Mexico border near Kermit south to Ft. Stockton, with a planned extension south to Sanderson. This planned extension was transferred to newly designated U.S. Highway 285 in 1935. In 1958, the route was renumbered as SH 18, to coordinate with its intersection with New Mexico State Road 18.

In 1975, SH 82 was designated over its current route in Jefferson County from SH 87 to Louisiana Highway 82. In 1987, the route was extended 2.1 miles (3.4 km) to SH 73 incorporating the former Texas State Highway Spur 214.
