Hyram Marks

Hyram A. Marks (8 June 1872 – c. 1957) was a rugby union player who represented Australia.

Marks, a lock, was born in Sydney, NSW and attended Sydney Grammar School and Sydney University. He claimed two international rugby caps for Australia and was the University rugby club's first Wallaby representative. His Test debut was against Great Britain, at Sydney, on 24 June 1899, the inaugural rugby Test match played by an Australian national representative side.

Due to funding constraints he was one of only six New South Wales players (Charlie Ellis, Bob McCowan, Lonnie Spragg, Peter Ward & Robert Challoner) selected to make the trip to Brisbane four weeks later for the second Test. His performance in that match was noted as excellent by the press.
