The Order of the Knights of Saint Columbanus (Irish: Ridirí Naomh Cholumba) is an Irish national Catholic fraternal organisation. Founded by Canon James K. O'Neill in Belfast, Ireland, in 1915, it was named in honour of the Irish saint, Columbanus. Initially established as a mutual benefit society for working class Catholics, it has developed into a fraternal benefit society dedicated to providing charitable services to all areas of the Irish community.
