KXLN-DT (channel 45) is a television station licensed to Rosenberg, Texas, United States, serving as the Houston-area outlet for the Spanish-language network Univision.

In February 1980, the Federal Communications Commission (FCC) designated three applications seeking channel 45 in Rosenberg for hearing.

Pueblo Broadcasting, owned by businessmen A.C. Peña and J. Adán Treviño, proposed the construction of Houston's first full-time Spanish-language outlet; previously, KRIV, an English-language independent, had carried some Spanish programming from the Spanish International Network, Univision's predecessor, or adjacent to prime time.

The bid had initially been prepared because SIN was interested in a station in the market and had approached local Hispanics to put together an application.

[9] On March 27, 2015, the station axed its morning newscast along with the local UniMás show Vive La Mañana for a regionalized morning newscast titled Noticias Texas Primera Edición that would air on Univision stations in Dallas, Houston, San Antonio, and Austin.

[16][17] Eleven days later, all Univision owned-and-operated stations, including KXLN, permanently added a "-DT" suffix to their call signs.
