Páirc Seán Mac Diarmada (pronounced [ˌpˠaːɾʲc ˈʃaːn̪ˠ mˠək ˈdʲiəɾˠmˠəd̪ˠə]) is a GAA stadium in Carrick-on-Shannon, County Leitrim, Ireland.

It was named for the Irish revolutionary Seán Mac Diarmada, one of the leaders of the 1916 Easter Rising.

(As there was in the early 1960s some debate among Irish scholars as to whether the genitive case should be used in commemorative namings, the nominative form was used and has been retained, rather than what would now be generally regarded as the grammatically correct form, Páirc Sheáin Mhic Dhiarmada.)

[2] In 2006–07, a major renovation created a 3,000-seat covered stand providing an unrestricted view of the football field.

The stand naming rights were then sold, and it is now called Ardán Mhic Shamhráin (using the genitive form).
