The Tour Jean-sans-Peur or Tour de Jean sans Peur, located in the 2nd arrondissement of Paris, is the last vestige of the Hôtel de Bourgogne, the residence first of the Counts of Artois and then the Dukes of Burgundy. The tower contained bed chambers and the grand stairway of the original residence, which stood next to it. It was completed between 1409–1411 by Jean sans Peur. The original hôtel occupied about a hectare of land, the boundaries of which are now marked by the rues Étienne Marcel, Montorgueil, Saint-Sauveur, and Saint-Denis. The tower itself is located at 20 rue Étienne Marcel, in the courtyard of an elementary school. It is one of the best surviving examples of medieval residential architecture in Paris. The tower is open to the public and presents changing expositions on life in the Middle Ages.

The 2nd arrondissement of Paris is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is colloquially referred to as deuxième. It is governed locally together with the 1st, 3rd and 4th arrondissement, with which it forms the 1st sector of Paris.
