This is a list of characters from the M*A*S*H franchise, covering the various fictional characters appearing in the novel MASH: A Novel About Three Army Doctors and its sequels, the 1970 film adaptation of the novel, and the television series M*A*S*H, AfterMASH, W*A*L*T*E*R, and Trapper John, M.D..

M*A*S*H is a popular media franchise revolving around the staff of the 4077th Mobile Army Surgical Hospital as they attempt to maintain sanity during the harshness of the Korean War.

Captain Benjamin Franklin "Hawkeye" Pierce is the lead protagonist in the MASH novels, film, and television series. The character was played by Donald Sutherland in the film and by Alan Alda on television, where he was the only character to appear in all 251 episodes. Between long, intense sessions of treating critically wounded patients, he makes the best of his life in an isolated Army camp by making wisecracks, drinking heavily, carousing, womanizing, and pulling pranks on the people around him, especially the unpleasantly stiff and callous Frank Burns and "Hot Lips" Houlihan. Although initially just one of an ensemble of characters, in the television series Hawkeye quickly became the center of the M*A*S*H unit's medical activity as well as the dramatic center of the series itself. In the series he is Chief Surgeon of the unit.

Pierce was born and raised in New England, most often mentioning Crabapple Cove, Maine, with a few references to Vermont. The character refers to having a sister but at other times identifies himself as an only child. His mother is deceased, and he is close to this father (in the novels lobsterman/fisherman "Big Benjy" Pierce, in the TV series Dr. Daniel Pierce). In the film Hawkeye is married with children, but in the TV series he is a bachelor and something of a ladies' man. He was given the nickname "Hawkeye" by his father, from the character in the novel The Last of the Mohicans, "the only book my old man ever read."
