Texas has the largest oil refining capacity in the United States.

Texas leads the United States in oil refining capacity, processing more crude oil than any other state. With its extensive infrastructure, experienced workforce, and proximity to oil-rich areas like the Permian Basin and Gulf of Mexico, Texas has become a hub for refining activities. Home to major refineries in Houston, Port Arthur, and Corpus Christi, Texas produces a significant portion of the nation’s refined petroleum products, including gasoline, diesel, and jet fuel. This concentration of refining capacity supports both U.S. domestic energy needs and export markets, reinforcing Texas’s critical role in the American energy sector.
