Eleanor of Viseu (d. 1525)
Eleanor of Viseu (2 May 1458 – 17 November 1525; Portuguese: Leonor de Viseu [liuˈnoɾ dɨ viˈzew]) was a Portuguese infanta (princess) and later queen consort of Portugal. She is considered one of her country's most notable queens consort and one of the only two who were not foreigners. To distinguish her from other infantas of the same name, she is commonly known as Eleanor of Viseu (after her father's title) or Eleanor of Lancaster (Lancaster, a name used by some Portuguese royals after her great-grandmother Queen Philippa of Lancaster). In Portugal, she is known universally as Rainha Dona Leonor.
