Marylhurst University was a private applied liberal arts and business university in Marylhurst, Oregon. It was among the oldest collegiate degree-granting institutions in Oregon, having awarded its first degree in 1897. Marylhurst was founded as St. Mary's College and run for many years by the Sisters of the Holy Names of Jesus and Mary. The former campus is located about nine miles south of Portland, Oregon on the Willamette River. Although Marylhurst University was a Roman Catholic school, it served students of all faiths and backgrounds. The university offered bachelor's degree completion programs in diverse liberal arts and business fields, and graduate degrees in such fields as business and nonprofit administration, food systems and society, teaching, art therapy counseling, divinity and applied theology, and interdisciplinary studies. After its establishment in 1893, Marylhurst became the first women's liberal arts college in the Pacific Northwest. In 1974, Marylhurst College became a co-educational institution, and in 1998 it was reorganized as Marylhurst University through the addition of new academic programs. The university closed at the end of the summer of 2018. Declining enrollment was given as the main reason, with enrollment having dropped from 1,409 to 743 in just four years, from fall 2013 to fall 2017. In recent years, the university's student population had peaked around 2,000 during the Great Recession of 2007–2009. Prior to the closure, however, Marylhurst's faculty challenged this narrative.
