Duke of Viseu (in Portuguese Duque de Viseu) was a Portuguese Royal Dukedom created in 1415 by King John I of Portugal for his third male child, Prince Henry the Navigator, following the conquest of Ceuta.

When Prince Henry the Navigator died without issue, his nephew, Infante Ferdinand of Portugal (King Edward of Portugal's younger son), who was already Duke of Beja, inherited the Dukedom of Viseu and, when his younger son became King of Portugal as Manuel I, this became a royal Dukedom.
