St. Theodore Catholic School is a private Roman Catholic school in St. Charles County, Missouri, United States.
St. Theodore was built in 1883 and named after Rev. Theodore Krainhardt. The original building was roughly 20feetx40feetft (xft) and would later be converted into a two-room school house with the addition of the church in 1900. The still-standing "old school" was built in 1913. It had 7 classrooms, two stories, a loft, a basement (used as a cafeteria), and two stairways. Two grades shared one classroom. Some classrooms were used as administrative offices throughout the years. Later, an elevator was added.
In 2000, the school was expanded, adding 6 classrooms, a cafeteria, a teacher's lounge, an administrator's office, and a large gym.
As of the 2011–2012 school year, about 215 students attend St. Theodore with a class size of 17–30.
