Pierre Terrail, seigneur de Bayard (1473 – April 30, 1524) is a French soldier, generally known as the Chevalier de Bayard.

Throughout the centuries since his death, he has been known as "the knight without fear and beyond reproach" (le chevalier sans peur et sans reproche).

He himself however, prefers the name given him by his contemporaries for his gaiety and kindness, "le bon chevalier", or "the good knight".
