Louis of Nassau, Lord of De Lek and Beverweerd was a Dutch soldier. He was the illegitimate son of Margaretha van Mechelen and Maurice, Prince of Orange, and so a collateral member of the House of Orange-Nassau. He was a Lord of the heerlijkheid De Lek and Beverweerd. From his father he inherited the estate of Beverweerd; and when his older brother Willem died in 1627 he inherited his estate as well.
