Arthur Joseph "Monkey" Gould (10 October 1864 – 2 January 1919) was a Welsh international rugby union centre and full back who was most associated as a club player with Newport Rugby Football Club. He won 27 caps for Wales, 18 as captain, and is considered the first superstar of Welsh rugby. Gould led Wales to the country's very first Home Nations Championship and Triple Crown titles in 1893; defining himself as a great player and captain in the match against England during the same tournament. Towards the end of his career Gould was at the centre of a controversy which saw Wales withdraw from international rugby for 12 months.

Gould was the most capped Welsh centre until Steve Fenwick of Bridgend beat the record at Lansdowne Road on 15 March 1980. He played 27 times for Wales, twice at full back and 25 at centre, ending his career against England on 9 January 1897. This last game was played in front of 17,000 supporters at Rodney Parade; Wales won 11–0. It was the 18th time Gould had captained Wales and this record stood until broken by Ieuan Evans in 1994.

A superb all round player and even-time sprinter with swerve, Gould could side-step and kick with either foot. He never ceased to practise to develop his fitness and skills. He was considered the outstanding player of his time.
