Dom Peter, Duke of Coimbra, KG (Portuguese: Pedro Portuguese pronunciation: [ˈpeðɾu]; 9 December 1392 – 20 May 1449) was a Portuguese infante (prince) of the House of Aviz, son of King Dom John I of Portugal and his wife, Philippa of Lancaster, daughter of John of Gaunt. In Portugal, he is known as Infante Dom Pedro das Sete Partidas [do Mundo], "of the Seven Parts [of the World]" because of his travels. Possibly the best-travelled prince of his time, he was regent between 1439 and 1448. He was also 1st Lord of Montemor-o-Velho, Aveiro, Tentúgal, Cernache, Pereira, Condeixa and Lousã.
