James Gordon Bennett Jr. (May 10, 1841 – May 14, 1918) was an American publisher. He was the publisher of the New York Herald, founded by his father, James Gordon Bennett Sr. (1795–1872), who emigrated from Scotland. He was generally known as Gordon Bennett to distinguish him from his father. Among his many sports-related accomplishments he organized both the first polo match and the first tennis match in the United States, and he won the first trans-oceanic yacht race. He sponsored explorers including Henry Morton Stanley's trip to Africa to find David Livingstone, and the ill-fated USS Jeannette attempt on the North Pole.
Bennett's controversial reputation is thought to be the inspiration behind the phrase "Gordon Bennett!", used as an expression of incredulity.
