WNAC-TV, channel 7, was a television station located in Boston, Massachusetts, United States. The station was owned by RKO General. Originally established in 1948, WNAC-TV signed off for the final time at 1:00 a.m. on May 22, 1982, due to improprieties by its parent company; it was replaced that morning with WNEV-TV (now WHDH), which operates on a separate license. The station was Boston's original CBS television affiliate; except for a period from 1961 to 1972 during which it was an ABC affiliate, WNAC-TV would remain with CBS until its replacement with WNEV-TV.
