Commodore is a census-designated place (CDP) in Green Township, Indiana County, Pennsylvania, United States.

Commodore was founded in 1919 by the Clearfield Bituminous Coal Corporation, a subsidiary of the New York Central Railroad.

It was named in honor of Commodore Cornelius Vanderbilt, founder of that railroad.

(Vanderbilt was known by the nickname or unofficial rank of Commodore due to his background as a riverboat owner.)

The town and its initial buildings were designed by Paul Gill, an engineer of the coal company.
