Arthur Flowers Harding (8 August 1878 – 15 May 1947) 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.

As an early forward, Harding was a surprisingly nimble player with a good running and passing style along with an excellent kicking ability.

Harding made his international debut for Wales against England at Blackheath in January 1902, while still in his first season for Cardiff.

After representing Wales for their fourth Triple Crown in 1905, Harding was chosen to face the Original All Blacks in the Match of the Century on the New Zealander's first tour of Britain.

After the end of his international career, Harding emigrated to Wanganui, New Zealand[3] becoming a station-master at Greymouth for several years.
