New Limerick is a town in Aroostook County, Maine, United States. The population was 523 at the 2000 census. The town was settled in 1775 and incorporated on March 18, 1837 from New Limerick Plantation. It received it name from the fact that many of its settlers had previously lived in Limerick in York County at the southern end of the state, which in turn was probably named after the Irish city of Limerick.
