The Doddie Weir Cup (Welsh: Cwpan Doddie Weir) is a perpetual rugby union trophy established in 2018 and contested between Scotland and Wales. The cup is named for former Scotland international lock Doddie Weir who suffers with motor neurone disease, and was created to raise awareness of the illness.
Wales won 21–10 in the inaugural match in Cardiff in November 2018. Wales are the current holders.
The cup was commissioned jointly by the Welsh Rugby Union and the Scottish Rugby Union and was designed by the Edinburgh silversmiths Hamilton and Inches. Doddie Weir commented on the trophy design, stating that the silversmiths "have done an absolutely fantastic job in making it with some big handles to emulate my massive ears!"
Weir set up a charity called My Name'5 Doddie Foundation to help fund treatments for motor neurone disease.
Neither the Welsh Rugby Union nor the Scottish Rugby Union originally intended to contribute any of the gate receipts from the inaugural match to the charity, but pressure from fans and in the media resulted in them eventually donating a six-figure sum.
