Irish Jamaicans are people of Irish ethnicity and Jamaican citizenship. Irish people are the second-largest reported ethnic group in Jamaica after African. Most Jamaicans with Irish heritage also have African ancestry. Historical Irish immigration to Jamaica occurred primarily through importation of Irish slaves after the Irish rebellion of 1641 and also constituted the second-largest recorded ethnic influx into the country. Some Irish slaves in Jamaica were indentured, but most more were complete chattel slaves imported by the tens of thousands by the English.
