WHDH, virtual channel 7 (UHF digital channel 42), is an NBC-affiliated television station licensed to Boston, Massachusetts, United States. The station is owned by Sunbeam Television, as part of a duopoly with Cambridge-licensed Disney Network affiliate WLVI (channel 56). The two stations share studios at Bulfinch Place (near Government Center) in downtown Boston and transmitter facilities in Newton, Massachusetts.

From 1982 to 1995, WHDH was Boston's CBS affiliate, inheriting the affiliation from its predecessor on channel 7, WNAC-TV. On January 2, 1995, WHDH switched to NBC, after CBS moved to WBZ-TV (channel 4) by virtue of a group-wide affiliation deal with its owner, Westinghouse Broadcasting (CBS and Westinghouse merged that November, making WBZ-TV a CBS owned-and-operated station).
