Centenary Quaich

The Centenary Quaich (/ˈkweɪx/) is an international rugby union award contested annually by Ireland and Scotland as part of the Six Nations Championship.

A "Quaich" is a Gaelic drinking vessel and has been presented to the winners of the fixture since 1989. It was introduced to mark the centenary of the founding of the International Rugby Football Board (founded 1887, which later became World Rugby). Since the introduction of the cup, Ireland have won it twenty-one times while Scotland have won it fourteen times, with one drawn fixture. The Quaich is not contested in matches between the two sides outside the Six Nations, e.g. pool matches in the 2019 and 2023 Rugby World Cup.

The Quaich is one of a number of similar cups contested for between individual teams as part of their international fixture list. Other examples within the Six Nations Championship include the Calcutta Cup (Scotland vs. England), the Millennium Trophy (England vs. Ireland), the Giuseppe Garibaldi Trophy (France vs. Italy) and the Auld Alliance Trophy between France and Scotland.

The contest for the Quaich has been notable for periods of dominance by one or other team; Scotland held the trophy for eleven years when first contested, including one draw where they retained the Quaich while Ireland have dominated from 2000 onwards, winning 22 out of 26 contests thereafter.

The current holders are Ireland who won an eighth successive contest after beating Scotland at Murrayfield Stadium on 9 February 2025.
