The Dublin Hospitals Rugby Cup is a rugby union competition contested by the teaching hospitals in Dublin since 1881. The competition has a claim to the oldest rugby union competition in the world. The United Hospitals Cup in London was started 6 years earlier, but 12 years were not played during the periods of World War I and World War II.
