Columba McDyer (13 January 1921 – 18 September 2001)[1] was a Gaelic footballer who played for Cavan and Donegal.
He played with the Cavan team that won the 1947 All-Ireland Senior Football Championship Final at the Polo Grounds in New York City.
This resulted in him becoming the first Donegal man to win an All-Ireland Senior Football Championship medal.
He also collected a Railway Cup medal with Ulster in 1942 and he also played in the same competition with Connacht.
He was also an early influence on Jim McGuinness, Donegal's future All-Ireland winning manager.
