WFSB (channel 3) is a television station licensed to Hartford, Connecticut, United States, serving the Hartford–New Haven market as an affiliate of CBS. Owned by Gray Television, the station maintains studios on Denise D'Ascenzo Way in Rocky Hill and a transmitter on Talcott Mountain in Avon, Connecticut.

Most of WFSB's programs are seen in Springfield, Massachusetts, over a low-power semi-satellite station, WSHM-LD (channel 33). That station is based at the facilities of sister station WGGB-TV (channel 40) in Springfield, although some master control and other internal operations are hubbed through WFSB.

WFSB also maintains a second sister station, WWAX-LD (channel 27), also licensed to Hartford. Known on-air as theWax, WWAX-LD mainly features simulcasts and repeats of WFSB's news programming, along with second runs of its syndicated shows and other Gray-produced programming. Its own third subchannel features a full-time automated feed of WFSB news briefs, headlines, current weather conditions, and other miscellanea known as Eyewitness News Now, which simulcasts on the station's website and mobile app.
