private coeducational institution of higher learning in Northfield, southeastern Minnesota, U.S. It is a liberal arts college affiliated with the Evangelical Lutheran Church in America. Named for Olaf II (Olaf II Haraldsson), the patron saint of Norway, St. Olaf's School was founded by Norwegian immigrants to southeastern Minnesota in 1874. The academy added a college department in 1886 and became St. Olaf College in 1889; the academy was dissolved in 1917. Total current enrollment is about 3,000.

St. Olaf's core curriculum includes sciences, arts, religion, multicultural studies, and humanities. Norwegian and Russian are among the languages taught at St. Olaf, which offers Bachelor of Arts degrees in some 40 majors, several teaching certifications, and four Bachelor of Music degrees. In addition to a major, students can add one of four areas of emphasis or one of some 20 interdisciplinary concentrations (such as Nordic studies, Middle East studies, and American racial and multicultural studies). St. Olaf houses the archives of the Norwegian-American Historical Association. The majority of students participate in the college's extensive off-campus programs, studying overseas or elsewhere in the United States. The college is noted for its annual Christmas festival, a tradition dating from 1912 and featuring four concerts by five student choirs and the college orchestra.
