Saint Martin's University is a private Benedictine university in Lacey, Washington. It was founded in 1895 as a boys' boarding school run by monks of the Benedictine Order. Saint Martin's began offering college-level courses in 1900 and became a degree-granting institution in 1940. The college became coeducational in 1965. In 2005, it changed its name from Saint Martin's College to Saint Martin's University. There is a Benedictine monastery on campus grounds and some members of the monastic community serve as professors.

Saint Martin's patron saint is Saint Martin of Tours, a fourth-century monk and missionary. The university and its founder, Saint Martin's Abbey, sit on 300 acres (1.2 km) of woodlands, trees, rocks, and meandering trails. The site was selected in 1894 by Abbot Bernard Locnikar of Saint John's Abbey, Collegeville, Minnesota, which was the mother abbey of St. Martin's Abbey. At a public auction on April 21, 1894, the wooded parcel that would become the Saint Martin's campus was purchased for $6,920.

Work began on Saint Martin's first building in January 1895. By late summer, a four-story structure housing both the school and a monastery was completed. The school at that time offered preparatory classes for boys, plus commercial and classical education for older boys and young men. Boarding students who came from outside of town also were housed in the campus' one large building. Today, that structure is referred to as Old Main and continues to house many of the university's classrooms and offices.
