Cascade College was a private, four-year, liberal arts college associated with the Churches of Christ. Located in Portland, Oregon, United States, it was a branch campus of Oklahoma Christian University. Its mission was to emphasize spiritual growth and career preparation. Because of Cascade's ongoing financial problems, Oklahoma Christian University closed Cascade at the end of the 2009 academic year.

Cascade had been founded as Columbia Christian College in 1956. For several years, Columbia had serious financial difficulties. Partially as a consequence, its regional accreditation was revoked. The school's board sought help from other colleges affiliated with Churches of Christ. Oklahoma Christian University agreed to fund the college as a branch campus. The newly renamed Cascade College opened in 1993 after its acceptance as a branch by Oklahoma Christian University, with 143 students attending the first semester.

As a branch campus of Oklahoma Christian, Cascade College was accredited by The Higher Learning Commission of the North Central Association of Colleges and Schools and was authorized by the State of Oregon to offer and confer academic degrees. In October 2008, plans were announced to close Cascade, because of financial difficulties, at the end of the 2009 academic year.
