KSJI (91.1 FM) is a radio station broadcasting a Christian Adult Contemporary format. Licensed to St. Joseph, Missouri, the station is owned and operated by the University of Northwestern - St. Paul, simulcasting KJNW "Life 88.5" from Kansas City. On July 1, 2024, the owned and operated affiliate Spirit FM left the St. Joseph market after 4 years prior to the acquisition of the independent religious radio station in July 2023.

Prior to being bought out by the then independent Spirit FM, KSJI was its own independent station, playing a CCM (Contemporary Christian Music) format known as "Joy 91.1/Joy 91.1 KSJI". The station was managed by Chris Meikel (who is now the Manager of Community Engagement for Bott Radio Network).
