St. Michael's Abbey is a community of Norbertine Canons Regular in Orange County, California, dedicated to preserving the time-honored traditions of the Catholic Church for the last 900 years, fostering a vibrant Christ-centered culture via the sacraments, and forming the priests of tomorrow through common life, common prayer and education. St. Michael's Abbey continues to grow quickly, ten-fold since its inception. It now numbers over 70 priests and seminarians.

Members of the abbey live a monastic life, that includes following the Rule of St. Augustine, chanting of the Divine Office and Mass every day along with an active apostolate. The abbey's principal apostolate is its preparatory school, a boys' boarding school (9-12) focused on forming the Catholic leaders of tomorrow. The priests are also involved in parish work, retreats and writing and translation of spiritual books.
