KWAX (91.1 FM) is a non-commercial classical music radio station in Eugene, Oregon, broadcasting to the Eugene-Springfield, Oregon area.

The station is a listener supported service of the University of Oregon.

KWAX started out in the late 1950s as a student managed and operated FM station, with studios and transmitter on the top floor of Villard Hall.

The initial transmitter was 10 watts, and hours of operation were somewhat irregular.

In 1966, a local FM station gave the university their old 250-watt transmitter when they upgraded.
