Holy Family under an Oak Tree or Madonna of the Oak Tree is an oil-on-panel painting by the Italian Renaissance artist Giulio Romano using a composition or underdrawing by Raphael. It is now in the Prado in Madrid. It is dated to c. 1518 by its stylistic similarities to other works produced by the two artists around that time such as La Perla (Prado). In the background is a valley reminiscent of that of the River Tiber, with a ruin on a hill to the left based on the Basilica of Maxentius or the Baths of Caracalla.
