The House of Della Rovere (literally "of the Oak Tree") was a noble family of Italy. Coming from modest beginnings in Savona, Liguria, the family rose to prominence through nepotism and ambitious marriages arranged by two della Rovere popes, Francesco della Rovere, who ruled as Pope Sixtus IV (1471–1484) and his nephew Giuliano (Pope Julius II, 1503–1513). Pope Sixtus IV built the Sistine Chapel, which is named for him. The Basilica San Pietro in Vincoli in Rome is the family church of the della Rovere.
