St. Dominic High School is a Catholic, college-preparatory high school serving the St. Louis area from its campus in O'Fallon, Missouri. Grounded in the Dominican tradition of prayer, study, community, and service, the school combines a four-year religion curriculum with faith-based student activities and regular Masses, Reconciliation services, and retreats. The school draws students from 35 parishes across four counties and sits on a large campus with facilities for athletics and performing arts, while planning an expansion of the sciences center. Origins trace to 1929 when Assumption High School opened in O'Fallon, and the Archdiocese of St. Louis established St. Dominic as a regional high school in 1962. In 2025, the school launched its on-campus student building trades program.
