KFTU-DT (channel 3) is a television station licensed to Douglas, Arizona, United States, serving as the Tucson market's outlet for the Spanish-language network UniMás.

The two stations share studios on Forbes Boulevard in Tucson; KFTU's transmitter is located on Juniper Flats Road northwest of Bisbee.

KFTU-DT is also rebroadcast on KUVE-DT's second digital subchannel in order to reach the entire market; this signal can be seen on channel 46.2 from a transmitter atop Mount Bigelow.

Master control and most internal operations for KFTU-DT and KUVE are based at the facilities of sister station KTVW-DT on 30th Street in southern Phoenix.

KFTU-CD began with an original construction permit granted on August 26, 1991, to Ponyland Broadcasting (later Venture Technologies Group) for a low-power television station to serve Tucson on UHF channel 25 with the callsign K25EA.

KFTU-CD did not apply for a companion channel for the digital conversion; as a low-power television station, it was exempt from the 2009 analog shutdown.
