The Henderson Cup was first presented in 1937 by Mr. RP Browne, a self-proclaimed "keen supporter of the Union", in memory of the late Mr. James Henderson.
Mr. Henderson was long-standing member, and later Chairman, of the NSWRU Council and its sub-committees from the turn of the century to the 1920s.
The 2009 Henderson Cup was won by Randwick who defeated West Harbour 20-19.
