KMSB (channel 11) is a television station in Tucson, Arizona, United States, affiliated with the Fox network. It is owned by Tegna Inc. alongside dual CW/MyNetworkTV affiliate KTTU-TV (channel 18); Tegna maintains a shared services agreement (SSA) with Gray Television, owner of CBS affiliate KOLD-TV (channel 13), for the provision of studio space and technical services and the production of local newscasts for KMSB.[2] The three stations share studios on North Business Park Drive on the northwest side of Tucson (near the Casas Adobes neighborhood). KMSB's lone transmitter is located atop Mount Bigelow; as a result of the transmitter's location, residents in the northern part of Tucson, Oro Valley, and Marana do not receive adequate reception of the station.

The station went on the air in 1967 as KZAZ, an independent station licensed to serve Nogales, Arizona, with a coverage area including Nogales and Tucson. Under the ownership of Roadrunner Television from 1976 to 1984, it developed into a homespun station with increased popularity and programming. Roadrunner sold the station to a company controlled by The Providence Journal Company in 1985; it affiliated with Fox in 1986. After producing local news programming in its first 14 years on air, local news was revived under Belo Corporation ownership in the 2000s. The station's separate local news department was dissolved when Belo entered into the SSA with KOLD-TV in 2011, with KOLD-TV producing several dedicated newscasts.
