Frank Cheadle (7 November 1885 – 12 May 1916) was an Australian pioneering rugby league footballer and AIF soldier who fell in World War I. A New South Wales interstate and Australian international representative centre, he was reputedly the first Sydney rugby union player to sign with the new breakaway league in its earliest formative days in late 1907. He played for New South Wales in the very first rugby match run by the newly created 'New South Wales Rugby Football League' which had just split away from the established New South Wales Rugby Football Union.
