Aoidmhín Mac Greágoir (c. 1883-1950) was a Gaelic scholar and folklorist. Born in England as Hugh MacMillan to a Protestant father and English mother, Mac Greágoir lived in Belfast and was a member of the Gaelic League. He contributed in An Claidheamh Soluis and An tUltach surviving Gaelic folklore, poetry and songs from Rathlin Island, the Sperrin Mountains of Derry and Inis Meáin in the Aran Islands. A member of the United Irish League as well as Belfast secretary for the Irish Volunteers, Mac Greágoir was likely a strong Irish nationalist.
