The Concordia University Archives is a climate-controlled storage facility located on the first floor of the F.W.J. Sylwester Library in the George R. White Library & Learning Center on Concordia's Portland campus. There are three archival collections housed in the Concordia University Archives:
- Concordia University
- The Northwest District of the Lutheran Church – Missouri Synod
- The Center for Volga German Studies at Concordia University
The Archives is a member of Archives West, a program offering of the Orbis Cascade Alliance, and its collections are also searchable there. The collections are open to the public by appointment.
