Irish Jamaicans are Jamaican citizens of Irish descent whose ancestors originated from Ireland. Irish people are the second-largest reported ethnic group in Jamaica, after Jamaicans of African ancestry. Population estimates range from 300,000 to 700,000, making Irish Jamaicans 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 forced laborers after the Irish rebellion of 1641 and also constituted the second-largest recorded ethnic influx into the country. Many Irish in Jamaica were voluntary indentured servants, but some were forced into indentured servitude and imported by the tens of thousands by the English.
