WRCB (channel 3), branded Local 3, is a television station in Chattanooga, Tennessee, United States, affiliated with NBC.

It picked up the NBC affiliation from WROM-TV in Rome, Georgia (now WTVC, located today in Chattanooga proper).

In 1968 the station moved to new facilities on Whitehall Road, on Chattanooga's north side, across the Tennessee River from downtown.

In 1979, Rust Craft merged with magazine publisher Ziff Davis, which, in turn, sold WRCB to current owner Sarkes Tarzian, Inc. of Bloomington, Indiana, in 1982.

As part of the SAFER Act,[9] WRCB kept its analog signal on the air until July 12 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
