KPNX (channel 12) is a television station licensed to Mesa, Arizona, United States, serving the Phoenix area as an affiliate of NBC. The station is owned by Tegna Inc., and maintains studios at the Republic Media building on Van Buren Street in downtown Phoenix (which also houses formerly co-owned newspaper The Arizona Republic); its transmitter is located atop South Mountain on the city's south side.
KPNX is also broadcast on satellite station KNAZ-TV (channel 2) in Flagstaff, which formerly was a separate NBC affiliate, and a network of low-power translators across northern and central Arizona.
Channel 12 was the second TV station on the air in the Phoenix area, starting in 1953. Originally established in Mesa itself, it was acquired by Phoenix radio station KTAR (620 AM) in 1954 in a maneuver that ended a contest over channel 3 in Phoenix and was co-owned with that outlet for 25 years. It has been owned by Tegna and its predecessor, Gannett, since 1979, when it became KPNX.
