Camillo Guerra (Naples 21 May 1797 – 10 March 1874 Naples) was an Italian painter, active mainly in Naples, Italy.
Born to a family of artists; his father, however, led a crew performing excavations at Pompei. Initially his father had wanted his son to become a lawyer, but Camillo became a student at the Royal School of Art under Costanzo Angelini .
In 1822, he won a prize that led him to a scholarship in Rome under Tommaso Conca, then under Vincenzo Camuccini. He was also influenced by Pietro Benvenuti and the reigning Neoclassicism. In 1829, he collaborated with E. Pistolesi in an eight-volume illustrated book about artifacts in the Vatican.
In 1827, he was nominated honorary professor of the Royal Institute of Art. In 1830, he was one of the artists that was commissioned to paint for the church of San Francesco di Paola. This neoclassic style church was meant by Francis I of the Two Sicilies to celebrate the restitution of the Bourbon dynasty and the expulsion of the Napoleonic Republic. Camillo’s contribution was an altarpiece depicting Glory of St Joseph (finished 1834). In 1834, he became professor at the Royal Academy. He painted a Virgin dei Raggi (now lost) for the church of San Nicola da Tolentino . For the former painting, he was paid 600 lira, and for the latter 400 lira. He painted an Apparition of the Virgin to Phillip Neri for the church of the Concezione, Naples. In the 1840s, with Gennaro Maldarelli, Filippo Marsigli, and Giuseppe Cammarano, he helped decorate rooms in the Royal Palace, now of the National Library in Naples (Biblioteca Nazionale Vittorio Emanuele III). Guerra frescoed the four Seasons. From 1846 to 1852, he painted an imposing fresco of the Celestial Paradise, harkening to a vision of St John the Evangelist, in the cupola of the Church of the Gerolomini (partly destroyed in 1943)
