Thibault Métezeau or Thibaut Métezeau (born 21 October 1533 at Dreux – died before 18 December 1586 in Paris)[1] was a French architect.

He was the younger brother of Jean Métezeau, also an architect.

[1] He spent the first part of his life in Dreux until 1569, when he moved to Paris, where he worked on the Tuileries Palace under Philibert de L'Orme, on the Valois chapel at the Basilica of Saint-Denis (1572–1582), and from 1578 as one of the contractors on the Pont Neuf.

He has been suggested as possibly the initial designer of the Hôtel de Nevers on the Left Bank (1580),[3] and the design of the Hôtel d'Angoulême (1585) has also been attributed to him.

[5] The historian of Paris Henri Sauval, writing around 1650 but published in 1724, attributed to him the design of the Salle des Antiques (Antiquities Room) in the Grande Galerie of the Palais du Louvre, although construction is not believed to have begun until 1595 under his son Louis Métezeau.
