WKSY-LD (channel 21) is a low-power television station in Rome, Georgia, United States.

Owned by Gray Media, it is a translator of Norcross-based Telemundo affiliate WKTB-CD (channel 47).

From its transmitter atop Mullinax Mountain in western Bartow County, in addition to cable coverage, WKSY-LD covers northwestern Georgia and northeastern Alabama, including Cartersville, Dalton and Ringgold, Georgia (the latter two are in the Chattanooga market); as well as Fort Payne, Alabama, but is within the Atlanta market.

Before Gray acquired the station in 2022,[3] the station carried several subchannels as "Sky 21", including a simulcast of WATC-DT from Atlanta and some local meetings, church services, and event and high school sports programming.

Upon completion of the sale to Gray, WKSY-LD became an extended satellite station of Telemundo affiliate WKTB-CD.
