Personal Coat of Arms of Prince Duarte I, 4th Duke of Guimarães.

The Infante Edward, 4th Duke of Guimarães (Portuguese pronunciation: [duˈaɾt(ɨ)]) (Lisbon, October 7, 1515 – Lisbon, September 20, 1540) was a Portuguese infante (prince); the sixth son of King Manuel I of Portugal and his wife Maria of Aragon.

He had as tutor André de Resende, who later wrote Duarte's biography. He also loved hunting and was quite a good musician.

In 1537 he married Isabella of Braganza, daughter of James, Duke of Braganza, who was dowried with the Dukedom of Guimarães in her own right. After the marriage, Infante Edward became the 4th Duke of Guimarães.

This marriage produced three children:

• Infanta Maria of Guimarães (1538-1577), married Alessandro Farnese, Duke of Parma and Piacenza.
• Infanta Catarina of Guimarães (1540-1614), Duchess of Braganza, married to John, 6th Duke of Braganza, she was a claimant of the throne of Portugal in 1580 (See: 1580 Portuguese succession crisis).
• Infante Edward, 5th Duke of Guimarães (1541-1576)

He is buried in the Monastery of Jerónimos in Lisbon.
