Jean-Antoine de Mesmes, called d'Avaux (1640–1709), was a French diplomat in the service of Louis XIV. He is probably best known for accompanying King James II of England in his Irish expedition. He also negotiated for France the Peace of Nijmegen, which ended the Franco-Dutch War (1672–1678). He was French ambassador in Venice, The Hague, Stockholm and finally The Hague again.
