KQMX (105.7 MHz) is a commercial radio station licensed to Lost Hills, California, and serving the Bakersfield metropolitan area. KQMX is owned by Alfonso De Alba, through licensee The De Alba Family Trust of 2000. It carries a Grupera and Regional Mexican format known as "Qué Buena 105.7."

KQMX is a Class B1 FM station. It has an effective radiated power (ERP) of 1,650 watts.

In June 2006, Magnolia Radio received a construction permit to build a new FM station on 99.5 in Lost Hills. The permit was then sold to Deportes y Musíca. The station remained unbuilt until 2010. That's when Grupo Multimedia bought the construction permits for KQMX and KRPH near Phoenix, Arizona.

For nearly a full year, from February 18, 2011, until the following February, KQMX was silent, pending a relaunch of the station by Grupo Multimedia/Deportes y Música. The station came back on the air on February 15, 2012; 13 years ago (2012-02-15).

Effective December 30, 2021, Grupo Multimedia sold KQMX to Alfonso De Alba.
