John Frederic Coulon (February 12, 1889 – October 29, 1973) was the World Bantamweight Champion from March 6, 1910, when he wrested the crown from England's Jim Kendrick, until June 3, 1914, when he was defeated by Kid Williams in Vernon, California.As there was some dispute over the sanctioning of the World Bantamweight Title by different boxing associations, other sources, particularly many American newspapers of the day, and the World Boxing Association, which became the National Boxing Association, recognized his first taking the bantamweight world championship on February 26, 1911, when he defeated Frankie Conley in twenty rounds in New Orleans, Louisiana.
