KWMU, (90.7 FM) is the flagship National Public Radio station in St. Louis, Missouri. Known on-air as St. Louis Public Radio, it is owned by and licensed to the University of Missouri–St. Louis. Its studios are located in Grand Center in midtown St. Louis.

St. Louis Public Radio's website states that its mission is "To be a trusted source of information and entertainment that opens minds and nourishes the spirit."

First signing on the air on June 2, 1972, KWMU has over 260,000 listeners in the St. Louis area. The station has 34 full-time employees, and 15 part-time, with hundreds of volunteers helping for special events. In 1983, it was the first radio station in St. Louis to play music from compact discs. A year later, it became the first radio station in the United States to broadcast Ambisonic programs. In 1992, the station increased its effective radiated power to 100,000 watts. In 1995, the station moved to an all-news format.

KWMU started broadcasting in HD Radio in 2006. In the fall of 2008, the station added a second digital stream, KWMU-2 The Gateway (Now Jazz KWMU-2), on its second digital subcarrier. It airs mostly alternative and world music. In the spring of 2010, the station added a third digital stream, Classical 90.7 KWMU-3, a 24-hour classical music service. Both stream live on the Internet.

On September 10, 2009, the station rebranded as St. Louis Public Radio and its website to STLpublicradio.org.

In September 2010, St. Louis Public Radio became the radio outlet for live broadcasts of the St. Louis Symphony Orchestra broadcasting its Saturday night concerts from Powell Symphony Hall.
