Henri I de Montmorency-Damville (15 June 1534 - 2 April 1614), Marshal of France, and Constable of France, seigneur of Damville, became Duke of Montmorency on his brother's death in 1579. He had been governor of Languedoc since 1563.

As a leader of the party called the Politiques he took a prominent part in the French Wars of Religion. In 1593 he was made constable of France, but Henry IV showed some anxiety to keep him away from Languedoc, which he ruled like a sovereign prince.
