João Afonso de Albuquerque, (c. 1304 – 28 September 1354), Juan Alfonso de Alburquerque in Spanish and nicknamed "o do Ataúde", 6th Lord of Alburquerque, was a member of the highest ranks of the nobility of the Kingdom of Portugal, an astute politician, and descendant from the royal houses of both Portugal and Castile, although through illegitimate lines.

Count of Alburquerque, Lord of Azagala, Codosera, Alconchel, Medellín, Meneses and Tiedra, he was the Alférez of King Alfonso XI of Castile and Leon (1333 – 1336), Chancellor of Castile between 1350 and 1353, and Mayordomo mayor of Infante Peter, later King Peter I of Castile, who is suspected of having him poisoned in 1354.
