About St. Mary's

St. Mary's Central High School is North Dakota's largest and oldest Catholic high school, with a rich history of educational excellence in the Bismarck-Mandan community.

In 1878, four sisters from the convent of St. Benedict in St. Joseph, Minnesota, arrived in Bismarck to staff what was then the St. Mary's Academy and Boarding School. In 1916, the first high school classes were offered and the spring of 1922 brought the first graduation at St. Mary's High School.

Today St. Mary's Central High School is home to 341 students in grades 9-12, offering high-quality academic instruction in a Catholic, Christian atmosphere. If you are interested in learning more about all that St. Mary's Central High School has to offer, please contact us.
