The Doddie Weir Cup (Welsh: Cwpan Doddie Weir[1]) is a perpetual rugby union trophy established in 2018 and contested between Scotland and Wales.

The cup is named after the former Scotland international lock Doddie Weir who was diagnosed with motor neuron disease in 2016 (he died from the disease in 2022, aged 52), and was created to raise awareness of the illness.

[4] 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!

"[5] Weir set up a charity called My Name's Doddie Foundation to help fund treatments for motor neurone disease.

[6] 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,[7] but pressure from fans and in the media resulted in them eventually donating a six-figure sum.
