KWEX-DT (channel 41) is a television station in San Antonio, Texas, United States, serving as the local outlet for the Spanish-language network Univision.

The station originally operated from studio facilities located on Network Boulevard (southwest of the present-day I-10) on the city's northwest side.

Azcarraga's family owned Mexico's highest-rated television network, Telesistema Mexicano (forerunner of Televisa), allowing KUAL to gain stronger programming.

With the move to the new studios on Network Boulevard, on July 29, 2013, KWEX-DT became the fifth television station in the San Antonio market to begin broadcasting its local newscasts in high definition.
