KEZR (106.5 FM) is a radio station licensed to San Jose, California and serving the San Francisco Bay Area. They program a Hot Adult Contemporary format as "Mix 106.5" and are owned by Alpha Media, through licensee Alpha Media Licensee LLC. Co-owned with KBAY, its studios are located in the heart of downtown San Jose at Park Center Plaza, and the transmitter is based from a site in Santa Teresa County Park.

KPSJ debuted in 1967 as KPLX, under the ownership of Bay Area broadcasting legend Les Malloy, from studios in the Hotel Sainte Claire in downtown San Jose. In December 1971, Malloy sold the station to PSA Broadcasting, a subsidiary of San Diego-based Pacific Southwest Airlines, for $330,000. In mid-1973, KPSJ's call letters were changed to KEZR; those call letters remained with the station into 2000s.

The station has programmed minor variations of adult contemporary music with the KEZR call letters since 1973.

This popular San Jose radio station has held many mixers and events with several famous artists including Sara Bareilles, Jason Mraz, and Augustana.

Before it was purchased by NextMedia Group, the station was briefly owned by CBS Radio, who moved the station from San Jose to San Francisco. Prior to that, it was owned for a long period by the Levitz family. During this period, particularly the 1990s, KEZR was a dominant force in Bay Area radio, regularly topping the Arbitron ratings.

NextMedia sold their 33 radio stations to Digity, LLC for a purchase price of $85 million; the transaction was consummated on February 10, 2014.

Effective February 25, 2016, Digity, LLC and its 124 radio stations were acquired by Alpha Media for $264 million.
