St. Croix Catholic School (SCCS) is a consolidated Kindergarten through 8th grade school located adjacent to St. Michael's Catholic Church in the town of Stillwater, a beautiful community in Minnesota's St. Croix River Valley.

Catholic education began in the St. Croix Valley in 1856, at which time St. Michael's School was founded by the Carondelet Order of the Sisters of St. Joseph from St. Paul. The neighboring parish, St. Mary's, opened a school in 1872. A local Benedictine Order of Sisters served St. Mary's School. The two schools merged in 1968, becoming St. Croix Catholic School. St. Charles' parish of Bayport joined the partnership that year as well.

The 2002-2003 school year opened a new door in the history of St. Croix Catholic School when the Dominican Sisters of St. Cecilia were invited to teach in the school and join the faithful of the St. Croix Valley in proclaiming the Truth of the Gospel to future generations. The sisters’ first convent in the area holds St. Dominic as the patron. Close to several lakes, the sisters enjoy the beautiful scenery of the St. Croix Valley.

Today, St. Croix Catholic School is a growing educational community with almost 400 students in grades Kindergarten through 5th grade and approximately 110 students in a 6th, 7th, and 8th grade Middle School.
