WCIA (channel 3) is a television station licensed to Champaign, Illinois, United States, serving as the CBS affiliate for the Central Illinois region. It is owned by Nexstar Media Group alongside Springfield-licensed MyNetworkTV affiliate WCIX (channel 49). Both stations share studios on South Neil Street/US 45 in downtown Champaign and also operate a sales office and news bureau on West Edwards Street near the Illinois State Capitol in Springfield. WCIA's transmitter is located west of Seymour, Illinois.
Since WCIA's over-the-air signal cannot be seen in western parts of the market (including Springfield and Jacksonville), it is simulcast in high definition on WCIX's second digital subchannel (49.2) from a transmitter in Clear Lake Township.
