Adolph of Cleves, Lord of Ravenstein (1425–1492) was the youngest son of Adolph I, Duke of Cleves, and of his wife Marie of Burgundy, a sister of Philip the Good, Duke of Burgundy.

Philip the Good of Burgundy and his wife, Isabel of Portugal, decided to arrange the marriage of their nephew Adolph, who became engaged to infanta Beatrice of Coimbra, daughter of Pedro, Duke of Coimbra.

Beatrice had taken refuge in Burgundy, under her aunt's protection, following the defeat of her father's army in the Battle of Alfarrobeira in Portugal in 1449.

In 1463, Adolph inherited Wijnendale Castle, where in 1482 Mary of Burgundy would fall from her horse suffering fatal injuries.

In 1454, he participated in the Feast of the Pheasant and became a knight of the Order of the Golden Fleece in 1456.
