WDHN (channel 18) is a television station in Dothan, Alabama, United States, affiliated with ABC and owned by Nexstar Media Group.

WDHN launched August 7, 1970, as the area's second television station and aired an analog signal on UHF channel 18.

WTVY was primarily a CBS affiliate, so conventional wisdom suggested that WDHN, as the second station in a small, two-station market, should have opted to affiliate with the NBC network rather than with ABC, because ABC was the smallest and weakest network and would not be anywhere near par with CBS and NBC in terms of ratings until later in the decade.

The Alabama side of the Dothan media market received a fairly strong signal from WSFA-TV, Montgomery's NBC station.

This is partly because for much of the analog era, WDHN only broadcast at 1.06 million watts, which was somewhat modest for a Big Four affiliate on the UHF band.

On June 1, 2020, WDHN began producing an hour-long 9 p.m. newscast for Fox affiliate WDFX, replacing a prior arrangement where news was provided by WSFA out of Montgomery.
