The Lansdowne Cup is a rugby union trophy. Established in 1999, the cup was donated to the Australian Rugby Union by the Lansdowne Club of Sydney as a perpetual trophy between Australia and Ireland. Like the Lansdowne Club, the cup is named after Dublin's famous rugby ground and was designed and made by Waterford Crystal of Ireland.
