Justinus van Nassau (1559 - Leiden, 1631) was the only extramarital child of William of Orange. He was a Dutch army commander known for unsuccessfully defending Breda against the Spanish, and the depiction of his surrender on the famous picture by Diego Velazquez.

His mother was Eva Elincx, William's mistress between his first and second marriage. William of Orange recognized Justinus and raised him with his other children.

Justinus studied in Leiden and became lieutenant-Colonel on May 17 1583. On February 28 1585 he became lieutenant-admiral of Zealand, and fought in 1588 against the Spanish Armada, capturing two galleons.

From 1601 until 1625 he was governor of Breda. In 1625 he had to surrender Breda to Spinola after a siege of 11 months. Justinus was allowed to leave for Leiden.
