The Expressway Authority of Thailand ( Thai: การทางพิเศษแห่งประเทศไทย) (EXAT) is a state enterprise under the Ministry of Transport. [1] It was founded in 1972, and operates Thailand's expressway (ทางพิเศษ thang phiset) system, which refers to (usually elevated) high-capacity controlled-access highways serving the Greater Bangkok area and some nearby provinces.

EXAT does not operate the separate Thai motorway network, which covers intercity controlled-access highways.
