KDTF-LD (channel 36) is a low-power television station in San Diego, California, United States, affiliated with the Spanish-language network UniMás.

It is owned by Entravision Communications alongside Class A Univision affiliate KBNT-CD (channel 17); it is also sister to Milenio Televisión affiliate XHDTV-TDT (channel 49).

The three stations share studios on Ruffin Road in San Diego's Kearny Mesa section; KDTF-LD's transmitter is located on San Miguel Mountain in Spring Valley.

This station was affiliated with Telefutura, the forerunner to UniMás, sometime in 2006, after talks reportedly broke down with sister station and former UPN affiliate XHUPN (channel 49, now XHDTV-TDT).

The station's signal is multiplexed: KDTF began broadcasting its digital signal on UHF channel 51 on May 14, 2009, and multicasting KBNT-CA and XHDTV.
