WKTC (channel 63) is a television station licensed to Sumter, South Carolina, United States, serving the Columbia area as an affiliate of MyNetworkTV.

The station is locally owned by WBHQ Columbia, LLC, and maintains studios in the Pontiac Business Center complex in Elgin and a transmitter on Rush Road (southeast of I-20) in rural southwestern Kershaw County.

On June 28, the station began running advertisements in the Columbia Free Times newspaper featuring the cast of one of MyNetworkTV's original telenovelas Desire, with the text "September 5 / It's a whole new ballgame," alongside a stylized "My 63" logo and the new call letters.

As a result of the change, WKTC pushed MyNetworkTV two hours later, running from 10 p.m. to midnight after CW prime time programming.

[10] WKTC regained the title of the only television station in the United States to carry both The CW and MyNetworkTV on its primary channel.

On May 29, 2019, The CW announced that it would move its Columbia affiliation from WKTC to the second subchannel of WIS (channel 10), effective September 30.

The station's signal is multiplexed: Prior to November 2009, WKTC carried the Retro Television Network on digital subchannel 63.2.
