Giacomo Boni (28 April 1688 – 1766) was an Italian painter of the late-Baroque period, active mainly in Genoa.
He was born in Bologna, and became a pupil of Marcantonio Franceschini, and later of the painter Carlo Cignani in Forlì. He returned and followed Franceschini to Genoa, then Crema, Piacenza, Lavino, Parma, and then Rome. He painted canvases for chapels in the Chiesa di San Filippo Neri in Genoa, and frescoes for their oratory. In Crema, he painted for the Chiesa del Carmine. In Piacenza, he painted in the church of Santa Maria del Popolo. He returned to Genoa in 1726, where he painted alongside Tommaso Aldrovandini in the Palazzo Durazzo. He painted the chorus of San Pancrazio for the nobleman Pallavicini. He also painted in the Palazzo Mari and in many others; and frescoed the vault of the oratory of Santa Maria della Costa, at Sanremo. In a chapel of San Giovanni in Parma he painted alongside Giuseppe Carpi.
