Denis Mary Bradley (25 February 1846 in Castleisland, County Kerry, Ireland – 13 December 1903 in Manchester, New Hampshire, USA) was an Irish-American Roman Catholic priest, who became the first Bishop of Manchester, New Hampshire. He is credited with co-founding Saint Anselm College with Abbot (OSB) in 1889 as Bradley had persistently requested the Benedictine monks of in Newark, New Jersey to establish a Roman Catholic college in the Diocese of Manchester. A faculty office building on the campus he helped found is named in his honor as Bradley House.
