Hazen is an unincorporated community in Jefferson County, in the U.S. state of Pennsylvania.[1]
Hazen was originally called Maysville, and named for John Mayes, the owner of a local store.[2] The present name of Hazen was adopted when the post office was established.[2] A post office opened at Hazen in 1882, and was operated until it was discontinued in 1982.[3]
