Arthur Flowers Harding was an English-born international rugby union player who played for and captained the Wales national team. Often called 'Boxer' Harding, he was a member of the Wales team for the famous Match of the Century, who beat the 1905 touring All Blacks in a game considered one of the greatest in the history of rugby union. He played club rugby for Cardiff and London Welsh and county rugby for Middlesex.

The Match of the Century is the unofficial name of a rugby union Test match played between Wales and New Zealand at Cardiff Arms Park on 16th December 1905 in front of a crowd of 47,000. The game was billed as the "Match of the Century" or "The World Championship" as it was a first meeting of the top two international teams.
