Bartolommeo Genga (1518–1558) was an Italian architect who was born in Cesena, Italy. He was the son of Girolamo Genga (1467–1551) and the brother-in-law of Giovanni Battista Belluzzi (1506–1554). At 20 years of age, Bartolommeo went to Florence, to continue the studies he commenced with his father. In Florence, he befriended Giorgio Vasari (1511–1574) and Bartolomeo Ammanati (1511–1592). After spending three years in Florence, he returned to his father, who was then building the church of San Giovanni Battista in Pesaro. Upon the death of his father in 1551, Bartolommeo assumed his father’s position with Duke Francesco Maria I della Rovere. Bartolommeo continued the building of San Giovanni Battista and built the Palace of Pesaro. He died in Malta at age forty in 1558.
