The Benevolent Irish Society (BIS) is a philanthropic organization founded on 17 February 1806, a month before the Feast of St. Patrick, in St. John's, Newfoundland. It is the oldest philanthropic organization in North America. Membership is open to adult residents of Newfoundland who are of Irish birth or ancestry, regardless of religious persuasion. The BIS is a charitable, fraternal, middle-class social organization founded on the principles of "benevolence and philanthropy", and had as its original objective the helping of the growing numbers of poor in St. John's, and providing the necessary skills which would enable the poor to better themselves.

By the 1820s, many BIS members were beginning to play prominent roles in the political life of Newfoundland and the Irish community in St. John's. By the 1840s the BIS had become so wealthy and influential that, next to the House of Assembly and the governor's council, the BIS was able to marshal considerable resources to address social problems and needs. In 1876 it sponsored the establishment in St. John's of the Irish Christian Brothers, and assisted with the maintenance of the St. Bonaventure's College and the opening of St. Patrick's School.

The greatest honour ever bestowed on the Society came in 1996 when the Taoiseach of Ireland , John Bruton, visited the BIS in St. Patrick's Hall on St. Patrick's Day.
