Hawkeye Pierce’s hometown, Crabapple Cove, is in Maine.
The fictional coastal community is part of Benjamin “Hawkeye” Pierce’s backstory in the M*A*S*H television series. His father, Dr. Daniel Pierce, practiced medicine there, and Hawkeye frequently refers to returning home to visit him. The setting helps contrast Hawkeye’s New England identity with his wartime life at the 4077th Mobile Army Surgical Hospital in Korea.
The character’s background varies slightly across M*A*S*H versions. The novel and film differ from the television series in details such as Hawkeye’s family life, while early TV episodes occasionally mention Vermont. Those continuity variations do not change the series’ standard identification of Crabapple Cove with Maine.
Crabapple Cove is fictional, so it is not a real Maine town to locate on a map. The name is part of the show’s recurring fictional geography, much like the 4077th itself is a fictionalized unit inspired by real Korean War MASH hospitals.
