The Secular Institute Pius X, or Pius X Secular Institute (ISPX), is a Catholic men's clerical secular institute of consecrated life of diocesan right headquartered in Charlesbourg, Quebec City, Canada.
It was established by Henri Roy in 1939 in Manchester, New Hampshire. A secular institute is an organization of individuals who are consecrated persons (professing the evangelical counsels of chastity, poverty and obedience) and live in the world, unlike members of a religious institute, who live in community.
