Girolamo Basso della Rovere (1434 - 1507) was an Italian Cardinal of the Roman Catholic Church.
Basso della Rovere was born in Albissola Marina, the son of Giovanni Basso (Marquess of Bistagno and Monastero) and his wife Luchina della Rovere of the House of della Rovere and sister of Pope Sixtus IV
He was Bishop of Albenga in 1472, and then Bishop of Recanati in 1476. He was created cardinal on 10 December 1477 by his uncle, Pope Sixtus IV.[1]
Between 1471 and 1484 he built a new family chapel in the Basilica of Santa Maria del Popolo in Rome, the same church that his relatives, Pope Sixtus IV and Domenico della Rovere, significantly rebuilt and embellished. The Basso Della Rovere Chapel was decorated by the favourite artist of the family, Pinturicchio, and his workshop. Girolamo's father, Giovanni Basso, was buried in the chapel.
