Arthur Chapman (June 25, 1873 - December 4, 1935) was an early twentieth-century American poet, newspaper columnist and author. He wrote a subgenre of American poetry known as Cowboy Poetry. His most famous poem was Out Where the West Begins. In 1919 Chapman moved to New York City, where he lived on the East Side of Manhattan. He took a job as a staff writer for the New York Tribune, which he held until his retirement in 1925. Chapman's first novel, Mystery Ranch (1921), combined western adventure with murder mystery.
