WMUR-TV, channel 9, is an ABC-affiliated television station located in Manchester, New Hampshire, USA. WMUR-TV is owned by Hearst Television, a subsidiary of the New York City-based Hearst Corporation, and has its studios on South Commercial Street in downtown Manchester. The station's transmitter is on the south peak of Mount Uncanoonuc in Goffstown, New Hampshire.

Manchester is considered to be part of the larger Boston television market; that city's ABC affiliate WCVB-TV is also owned by Hearst. WMUR-TV shares common coverage areas with two other sister stations, WMTW-TV in Portland, Maine; and WNNE in Hartford, Vermont.

During election seasons, WMUR is well known for organizing and producing candidate debates for ABC News, as well as CNN, before the first United States presidential primary; the debates have been held at Saint Anselm College.

Since August 22, 1994, WMUR has operated three repeaters in the northern parts of New Hampshire. Until 2001, two of the stations aired programming from Fox but simulcast channel 9's newscasts (the third one carried all WMUR programming, including ABC network programming). The two Fox stations started simulcasting WMUR when WMTW (at that time separately owned) moved its transmitter off Mount Washington. Since all three stations are low-powered, they were exempt from the transition to digital-only broadcasting on June 12, 2009.
