From historic fraternal orders to modern lay movements, Catholic organizations are where the faith comes alive in community. Discover the right apostolate for you — then find a local chapter and connect with members near you.
For two thousand years, Catholics have gathered into organizations, apostolates and movements to live the faith more fully together than they ever could alone. These Catholic groups carry distinct charisms — gifts of the Holy Spirit expressed through a particular way of praying, serving and evangelizing. Some are ancient; many of today's most vibrant Catholic lay organizations were born in the last century as the Church called every baptized person, not only priests and religious, to share in her mission.
A fraternal order like the Knights of Columbus channels charity and brotherhood among Catholic men. An apostolate like the Legion of Mary sends laypeople out to visit the lonely and pray with the sick. Renewal movements such as Cursillo and Regnum Christi form disciples through retreats and small groups, while the Secular Franciscans weave the spirit of St. Francis into ordinary family and working life. Together these Catholic movements show that holiness is meant to be lived in community, in the world.
Catholic Connect exists to help you take the next step. Reading about these organizations is one thing; meeting their members is another. Our app maps the Catholics, groups and events around you, so you can move from curiosity to a real local chapter and real friendships.

Catholic organizations and movements are communities — many led by laypeople — that gather Catholics around a shared spirituality, charism or mission. They include fraternal orders like the Knights of Columbus, apostolates like the Legion of Mary, and renewal movements like Cursillo and Regnum Christi. Each offers prayer, formation, fellowship and concrete service to the Church.
Most Catholic organizations welcome new members through a local chapter, council or group tied to a parish or region. The usual path is to attend a meeting or introductory event, get to know current members, and then go through whatever formation or admission step the group uses. Catholic Connect helps you find members and chapters near you so that first step is easy.
Some are open to everyone, while others focus on a particular state in life — for example, the Knights of Columbus is for Catholic men, and Legatus is for Catholic executives and business owners. The directory below notes who each organization is for so you can find the right fit.
