The Mabee-Gerrer Museum of Art is a non-profit art museum in Shawnee, Oklahoma, USA. It is located on the former Oklahoma Baptist University Green Campus, being the campus of the former St. Gregory's University. In June of 2024, over six years since the closing of St. Gregory's University, it was announced that the university land would return to the monks of St. Gregory's Abbey. The museum operated independently of St. Gregory's University and Oklahoma Baptist University and survived the closure and operational changes of the campus grounds.
