Effrinagh (in Irish: Ifreannach) is a townland in County Leitrim.

Effrinagh is a place about five miles east of Carrick on Shannon.

It remains a quiet place in spite of its proximity to the bustle and hustle of Carrick.

It is dotted with lakes and traversed by boreens (from the Irish bóithrín, meaning a small road).

James Gralton came from Effrinagh, where he built his Pearse-Connolly Hall before he was deported to New York City.
