St. Michael's Catholic Preparatory School (formerly St. Michael’s Catholic Academy) is a private college preparatory school in Barton Creek, a community in unincorporated Travis County, Texas (Greater Austin),[1] with an enrollment of approximately 750 students in grades PreK-12.

In 2015 and 2016, St. Michael's won the Class 4A Henderson Cup, awarded by the Texas Association of Private and Parochial Schools for excellence in academics, fine arts and athletics.

Many former St. Michael's student-athletes have played, or are now playing, Division 1 sports at the college level including American football, baseball, basketball, track and field, golf, volleyball, cross country, baseball and soccer.

From 1972 to 1984, Austin was the only sizable city in the USA without a Catholic high school.

A small group of parents and Catholic lay leaders commissioned a study that ultimately revealed enthusiasm in the Austin community for such a school.
