KNAU (88.7 FM) is a radio station broadcasting a classical music and news/talk and information format. Licensed to Flagstaff, Arizona, United States, KNAU and its sister stations serve Northern Arizona.

The station is currently owned by Northern Arizona University (NAU) and features programming from National Public Radio, Public Radio International, and American Public Media, among other content providers. NAU also owns KPUB (91.7 FM), a station devoted to talk programming, and student-run low-power station KLJX-LP (107.1 FM). KNAU's programming is heard on KNAA (90.7 FM) in Show Low and on five translators in northern Arizona, as well as online. Broadcasting activity at NAU began in 1962 as a 10-watt AM station, run by students, with student-built transmitter and antenna atop Sechrist Hall. The format was Top 40, playing popular music of the day. It was switched to a carrier current service in 1968, making it available only in campus buildings rather than over the air. The FM station was approved in 1968 and began broadcasting in December 1970 as KAXR. It was a 10-watt station that aired some arts programming as well as student DJ-selected music. In the early 1980s, the station transformed from a local outlet into a regional public radio station, which included a frequency change and power increase to 100,000 watts in 1983, expanded facilities and staff, affiliation with NPR, and the construction of new transmitters.
