KUAN-LD (channel 48) is a television station licensed to Poway, California, United States, serving as the San Diego–area outlet for the Spanish-language network Telemundo.

Despite KUAN-LD legally holding a low-power license, it transmits using KNSD's full-power spectrum from an antenna southeast of Spring Valley.

KUAN is known on-air as Telemundo 20; as with KNSD's main branding, it is derived from its channel 20 cable position on Charter Spectrum, Cox Communications and AT&T U-verse.

The station signed on in 1980 as K48AL, originally operating as a translator of Los Angeles–based multicultural independent KSCI for the San Diego market, airing on low-power analog channel 48.

On September 12, 2017, NBCUniversal acquired KUAN from NRJ TV, LLC, the owner of KSCI, for $650,000;[7] the sale was completed on December 21, 2017.
