Macroom Mountain Dew Festival was a music festival in Ireland, which was held between 1976 and 1982.

Taking place in the grounds of a 19th-century castle in County Cork,[1] it is considered to have been the first rock festival in Ireland.

[2][3] The festival is named for Macroom's reputation as a centre for production of poitín ("mountain dew").

[4] Its organisation was spearheaded by publican and undertaker John Martin Fitz-Gerald, who approached Rory Gallagher’s brother and manager, Donal, about staging the open air concert.
