Toutens (Occitan: Totens) is a commune in the Haute-Garonne department in the Occitanie region in Southwestern France.

The De Ver family had lived in a château in Toutens since before the mid-16th century, certainly before 1554 and possibly 1503 or even earlier.

Then the Marquis de Toutens were more plainly styled the Seigneur de Toutens, feudal lords with considerable rights to collect income and levy justice in their fiefdom.

Then on 28 June 1580, during the French Wars of Religion, the Vicomte de Turenne, a friend and ally of the future King Henry IV of France, led a Protestant (Huguenot) army and attacked several châteaux and forts in the area around Toutens.

[4] Its inhabitants are called Toutensois (masculine) and Toutensoises (feminine) in French.
