James William Flavin Jr. (born Portland, Maine 14 May 1906 - died Los Angeles, California 23 April 1976) was an American character actor whose career lasted nearly half a century.

Flavin was the son of a hotel waiter of Canadian-English extraction and a mother, Katherine, whose father was an Irish immigrant. Thus Flavin, well-known in Hollywood as an "Irish" type, was only one-quarter Irish. Flavin was born and raised in Portland, Maine, a fact that may have enriched his later working relationship with director John Ford, also a Portland native.

He attended the United States Military Academy at West Point but, contrary to some sources, did not graduate. Instead he dropped out and returned to Portland and drove a taxi. Then as now, summer stock companies flocked to Maine each year, and in 1929 Flavin was asked to fill in for an actor. He did well with the part and the company manager offered him $150 per week to accompany the troupe back to New York. Flavin accepted and by the spring of 1930 was living in a rooming house at 108 W. 87th Street in Manhattan. Flavin didn't manage to crack Broadway at this time; his Broadway debut would not occur for another 39 years, in the 1971 revival of The Front Page, in which he played Murphy and briefly took over the lead role of Walter Burns from star Robert Ryan. .

Flavin worked his way across the country in stock productions and tours, arriving in Los Angeles around 1932. He quickly made the transition to movies, landing the lead role in his very first film, a Universal serial, The Airmail Mystery (1932). He also landed his leading lady, marrying the serial's female star Lucile Browne that same year. However, the serial marked virtually the last time that Flavin would play the lead in a film. Thereafter, he was restricted almost exclusively to supporting characters, many of them without so much as a name. He specialized in uniformed cops and hard-bitten detectives, but played chauffeurs, cabbies, and even a 16th-century palace guard with aplomb. Flavin appeared in nearly 400 films between 1932 and 1971. He appeared in almost 100 television episodes before his final appearance, as President Dwight D. Eisenhower in Francis Gary Powers: The True Story of the U-2 Spy Incident (1976).

Flavin died of a heart ailment at Cedars-Sinai Medical Center in Los Angeles on April 23, 1976. His widow Lucile died 17 days later. They were survived by their son, William James Flavin, subsequently a professor at the United States Army War College. James and Lucile Browne Flavin were buried at Holy Cross Cemetery in Culver City, California.

Although he graduated from West Point, James Flavin decided on an acting career instead of the military. After touring with several stock and repertory companies, he arrived in Hollywood and broke into films in the early 1930s. A fast-talking, granite-jawed Irishman, Flavin appeared in hundreds of films during his career and was often cast as a big-city homicide detective, street cop, prison guard or Marine sergeant. One of Flavin's closest friends, oddly enough, was legendary cheapo producer Sam Katzman. Flavin was married for more than 40 years to actress Lucile Browne; he died in 1976, and she died two weeks after he did.

Jut-jawed and jaunty-looking Irish-American character actor appeared in countless Hollywood films of the 1930s and '40s in which he almost always portrayed a keeper of order: e.g., a ship's second mate or a US Marine platoon sergeant or a big-city police investigator. The only exception to his good-guy rule was his brief appearance as a thug in the comedy )Brother Orchid (1940)_.
