KTLA (channel 5) is a television station in Los Angeles, California, United States, affiliated with The CW. It is the largest directly owned property of Nexstar Media Group. KTLA's studios are located at the Sunset Bronson Studios on Sunset Boulevard in Hollywood, and its transmitter is located atop Mount Wilson. It is the second-largest CW affiliate by market size that is not owned and operated by the network's co-owner, Paramount Global (the largest being sister station WPIX in New York City).

KTLA was the first commercially licensed television station in the western United States, having begun operations in January 1947. Although not as widespread in national carriage as its Chicago sister station WGN-TV, KTLA is available as a superstation via DirecTV and Dish Network (the latter service available only to grandfathered subscribers that had purchased its a la carte superstation tier before Dish halted sales of the package to new subscribers in September 2013), as well as on cable providers in select cities within the southwestern United States and throughout Canada.

As of 2015, KTLA operates an internet-only news radio channel on iHeartRadio.
