KFUO (850 kHz) is a non-commercial AM radio station licensed to Clayton, Missouri, U.S., and serving Greater St. Louis. It has a Christian radio format. Owned and operated by The Lutheran Church – Missouri Synod (LCMS), its radio studios and offices are in the LCMS headquarters in Kirkwood, Missouri.

KFUO is a daytimer station, powered at 5,000 watts, using a non-directional antenna from a transmitter site on the grounds of the Concordia Seminary in Clayton. Because it operates on the same frequency as Class A KOA in Denver, it must sign off at sunset. As such, the on-air hours vary depending on time of year. KFUO operates between 80 1/2 and 102 1/2 hours per week, depending on the times of sunrise and sunset in Denver.

The station's FM translators at 92.7 MHz, 104.5 MHz and 105.3 MHz, relay station KFUO and streaming at kfuo.org, play sacred music when the 850 signal is off the air.

KFUO broadcasts using HD Radio technology.
