Captain H. M. "Howling Mad" Murdock is a fictional character in the 1980s action/adventure television series, The A-Team. He was played by Dwight Schultz. The character of Murdock was almost written out of the series before it aired, as the producers found the character too "over the top". The popularity of the character among the test audience however convinced the producers to keep the part of Murdock. Murdock appeared on The A-Team from the series beginning in 1983 until its cancellation in 1987.

The A-Team is a group of ex-United States Army Special Forces who were wrongly convicted of a crime during the Vietnam War. Managing to escape from the military police, they fled to Los Angeles, where, as fugitives, the A-Team work as soldiers of fortune, using their military training to fight oppression or injustice. Murdock, along with Hannibal Smith, B. A. Baracus, and Templeton "Faceman" Peck make up the A-Team. Although Murdock was not convicted of any crime, as the other three were, he is still a full-fledged member of the team.
