WCVB-TV (channel 5) is a television station in Boston, Massachusetts, United States, affiliated with ABC and owned by Hearst Television. The station's studios are located on TV Place (off Gould Street near the I-95/MA 128/Highland Avenue interchange) in Needham, Massachusetts, and its transmitter is located on Cedar Street, also in Needham, on a tower shared with several other television and radio stations.

Nearby Manchester, New Hampshire, is considered part of the Boston media market, making WCVB-TV part of a nominal duopoly with WMUR-TV (channel 9), that city's ABC affiliate; however, the two stations maintain separate operations.

WCVB is also one of six Boston television stations that are carried by satellite provider Bell Satellite TV and fiber optic television provider Bell Fibe TV in Canada. Since 2010, midday and weekend late newscasts, along with World News Now, are overlaid with Canadian paid programming on those providers; however, the latter has carried the normal WCVB-TV feed in recent years.
