Reginald Heber Macaulay (24 August 1858 – 15 December 1937) was an amateur English footballer who won the FA Cup with Old Etonians in 1882 and made one appearance for England in 1881 playing as a forward.
Macaulay was born in Hodnet, Shropshire, son of a rector of the parish who was cousin of the historian Lord Macaulay. Classical scholar George Campbell Macaulay was a brother, through whom author Rose Macaulay was his niece. His forenames appear to have been given after Bishop Reginald Heber (1783-1826), also an earlier rector of Hodnet.
Macaulay was educated at Eton College, where he played for the college "soccer" team in 1878.
He went up to King's College, Cambridge where he won a Cambridge University "Blue" in 1881 and 1882. He was also an athlete and represented the university between 1879 and 1882 at the high jump and the quarter mile, becoming the Amateur Athletic Association high jump champion in 1879. Academically, he graduated as BA 1st Class in 1882, and was awarded an honorary MA in 1914.
