WSAU (550 kHz) is an AM radio station broadcasting a conservative talk radio format. It is licensed to Wausau, Wisconsin, and is simulcast on WSAU-FM at 99.9 MHz in Stevens Point (licensed to Rudolph) and on FM translator W236CO in Marshfield at 95.1. It is owned by Wausau-based Midwest Communications, with studios on Scott Street.

WSAU is a Class B AM station. It is powered at 15,000 watts by day and 20,000 watts at night, using a directional antenna with a four-tower array. The AM transmitter is along County Highway X in Kronenwetter, Wisconsin.

It started as WLIN in Merrill, Wisconsin, in 1948, preceded the year before by an FM station (now WIFC). It was owned by United States Representative Alvin E. O'Konski. It moved to Wausau in 1952 as that city's second radio station. WSAU, then at 1400 AM, acquired the 550 frequency in 1958 in a facility upgrade. Midwest has owned WSAU since 1996.
