Selwyn Hanam Biggs (June 1872 – 12 January 1943) was a Welsh international rugby union fly-half who played club rugby for Cardiff and county rugby for Glamorgan. Both Biggs and his brother Norman played international rugby for Wales, though they never played in the same match for Wales together. Biggs was described at the time as a 'certain tackler' and a 'fast, good dodger'. Biggs also played cricket for Glamorgan and was part of the team to face the touring South Africans in 1895.
