Fra' Pietro del Monte (1499 − 26 January 1572) was an Italian nobleman who was the 50th Grand Master of the Order of Saint John from 1568 to 1572.

During the Great Siege of Malta of 1565, del Monte was in command of Fort Saint Michael in Senglea.

Del Monte managed to hold the fort for 55 days until the arrival of de Toledo's relief force on 8 September.

Del Monte was appointed as Grand Master on 23 August 1568, three days after the death of his predecessor Jean Parisot de Valette, after whom the Malta capital is named.

During his rule as Grand Master, del Ponte continued the construction of the new capital Valletta.
