George Michael Cohan (July 3, 1878 – November 5, 1942) was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and theatrical producer.

Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans". Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan wrote more than 50 shows and published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag". As a composer, he was one of the early members of the American Society of Composers, Authors, and Publishers. He displayed remarkable theatrical longevity, appearing in films until the 1930s and continuing to perform as a headline artist until 1940.

Known in the decade before World War I as "the man who owned Broadway", he is considered the father of American musical comedy. His life and music were depicted in the Oscar-winning film Yankee Doodle Dandy (1942) and the 1968 musical George M! A statue of Cohan in Times Square, New York City commemorates his contributions to American musical theatre.

He died of cancer at the age of 64 on November 5, 1942, at his Manhattan apartment on Fifth Avenue, surrounded by family and friends. His funeral was held at St. Patrick's Cathedral, New York, and was attended by thousands of people, including five governors of New York, two mayors of New York City and the Postmaster General.

The honorary pallbearers included Irving Berlin, Eddie Cantor, Frank Crowninshield, Sol Bloom, Brooks Atkinson, Rube Goldberg, Walter Huston, George Jessel, Connie Mack, Joseph McCarthy, Eugene O'Neill, Sigmund Romberg, Lee Shubert and Fred Waring.Cohan was interred at Woodlawn Cemetery in The Bronx, New York City, in a private family mausoleum he had erected a quarter century earlier for his sister and parents
