Arthur Harper Daniels (12 September 1922 – 4 October 2001) was a Welsh rugby league footballer. Arthur Daniels was born in Pontyberem, Carmarthenshire, Wales. In 1945, he was one of three Welshmen, all from the Llanelli area, who had trials with the Halifax rugby league club (Heritage № 546). A wing, he made a relatively slow start to his rugby league career, which was interrupted with a period in the armed forces. Following a big improvement in his form in 1948–49, he was by 1949 an important part of the Halifax side.
