Boer ( /ˈbʊər/, /ˈboʊ.ər/, or /ˈbɔər/; Afrikaans: [ˈbuːr]) is the Dutch and Afrikaans word for farmer, which came to denote the descendants of the Dutch-speaking settlers of the eastern Cape frontier in Southern Africa during the 18th century, as well as those who left the Cape Colony during the 19th century to settle in the Orange Free State, Transvaal (which are together known as the Boer Republics), and to a lesser extent Natal. Their primary motivations for leaving the Cape were to escape British rule and extract themselves from the constant border wars between the British imperial government and the native tribes on the eastern frontier.

The Trekboers, as they were originally known, were mainly of Dutch origin and included Calvinists, Flemish and Frisian Calvinists, as well as French Huguenot and German and British protestants who first arrived in the Cape of Good Hope during the period of its administration (1652 – 1795) by the Dutch East India Company (Verenigde Oostindische Compagnie or VOC). Lesser migrations of Scandinavians, Portuguese, Greeks, Italians, Spanish, Polish, Scots, English, Jews, Russians and Irish immigrants also contributed to this ethnic mix.
