Stetson is an American brand of hat manufactured by the John B. Stetson Company. "Stetson" is also used as a generic trademark to refer to any campaign hat, particularly in Scouting.

The John B. Stetson Company, founded by John B. Stetson in 1865, was the maker of the Stetson cowboy hats, but ceased manufacturing in 1970. Stetson hats are now being manufactured in Garland, Texas, by Hatco, Inc., who also produce Resistol and Charlie 1 Horse hats.
