Irish Jamaicans are Jamaican citizens who trace their ancestry from the Republic of Ireland or Northern Ireland. Irish people are the second-largest reported ethnic group in Jamaica after African. Population estimates range from three-hundred thousand to seven-hundred thousand, making Irish Jamaicans to constitute up to 25% of Jamaica's population. 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 were complete chattel slaves imported by the tens of thousands by the English.
