XHWX-TV is a television station in Monterrey, Nuevo León and Saltillo, Coahuila. Broadcasting on analog channel 4 and digital channel 39 in both cities, XHWX is a transmitter of the Azteca Trece network and the key station in the Azteca Noreste regional system, which provides regional news and sports content to Azteca's stations throughout northeastern Mexico.

The first XHWX concession was awarded in 1980 to Corporación Mexicana de Radio y Televisión (the Mexican government's Canal 13 network).[2] The original concession called for a station on channel 22 (later occupied by XHMOY-TV), but the station was allowed to slot into channel 4 when XEFB-TV was moved to channel 2.
