Saint Michael's Academy is an American day and boarding school for boys and girls from kindergarten through twelfth grade located in Spokane, Washington, United States, and administered by the Congregation of Mary Immaculate Queen, a Sedevacantist Traditionalist Catholic religious congregation.

In September 1978, the boys high school moved to Mount Saint Michael in Spokane, Washington.

In 1990, William Mashburn established the first boys’ basketball team, which was the first ever athletics offered at the High School.

Teachers were complaining that students were gone too long from the classroom and the much quieted resentment about the sports program gained significant momentum with the faculty.

Due to these facts "St. Michael's decided to bring back most of these sport's including baseball, cross-country, basketball, and softball, in the upcoming 2019–2020 school year.
