KJZZ (91.5 FM, "K Jazz") is a National Public Radio member station in Phoenix, Arizona. Owned by Rio Salado College, it operates from studios on the college's campus in Tempe. KJZZ serves the Valley of the Sun with NPR programming from 3:00 a.m. to 8:00 p.m. on weekdays, 5:00 a.m. to 7:00 p.m. on Saturdays, and 5:00 a.m. to 5:00 p.m. on Sundays. At all other times a variety of music programs are available playing jazz and blues. KJZZ is sister station to the area's main classical music station, KBAQ.

KJZZ signed on in the early 1970s, broadcasting from the campus of Mesa Community College, in the Maricopa County Community College District, with the call letters KMCR for Mesa College Radio. In 1985 the call letters were changed to KJZZ to reflect the jazz musical programming featured by the station. Within a few years, the station was transferred to be under the supervision of Rio Salado College, also in the Maricopa County Community College District, as part of a district reorganization: Rio Salado College having been created as the "campus without walls" and being the umbrella for all classes and other academic activities not specifically offered at one of the district's physical campuses.

KJZZ produces several programs, including a weekly call-in talk show, Here and Now, hosted by Phoenix journalist Steve Goldstein which includes calls and e-mails from listeners.

In the Spring of 2008, the station produced The Aaron Brown Show, a pilot program hosted by former CNN news anchor Aaron Brown.

Also heard on KJZZ (as well as several other public radio stations in the southwest and Texas) are unique news stories under its program entitled Fronteras: The Changing America Desk.[2] This entity is one part of an initiative of the Corporation for Public Broadcasting (CPB) that created seven Local Journalism Centers (LJCs) to pool the resources of public media stations across the country in FY2009.[3] These LJCs hire their own reporters and editors and concentrate on a specific area. Fronteras represents the Southwest LJC and focuses primarily on cultural and demographic shifts in the southwest U.S. and stories began airing in 2010. Other topics heard on Fronteras include immigration and the U.S./Mexico border. According to the CPB, Fronteras' Southwest LJC and the remaining LJCs were expected to become self-sufficient after 2 years.[4]
