Campion Jesuit High School was a Jesuit boarding school for boys in Prairie du Chien, Wisconsin, named for the Jesuit martyr Edmund Campion. The school operated from its founding in 1880 until closing in 1975, and educated several notable figures during its existence. The former school's campus now houses a prison operated by the state of Wisconsin Department of Corrections. The school operated independently of the Roman Catholic Diocese of La Crosse.
