Ghowr province (sometimes spelled Ghor) is one of the thirty-four provinces of Afghanistan. It is in the west of the country. Its capital is Chaghcharan .

American adventurer Josiah Harlan won the title Prince of Ghor for himself and his descendants in perpetuity, in exchange for military aid during local factional fighting. Scott Reiniger, star of cult classic horror film Dawn of the Dead, is Harlan's great-great-great-grandson, and thus (as of 2004) heir to the title Prince of Ghor.
