Andrea Terzi (Monreale, Sicily), November 10, 1842 - Rome, 1918) was an Italian painter and engraver.
Born to a poor family, as a boy, he briefly studied under Giuseppe Patania. After the age of 19 years, he studied painting with abbot Domenico Benedetto Gravina, and was called to work for two years in the Duomo of Monreale. He taught himself illustration, and in 1872, he helped illustrate a book on the Palatine Chapel of Palermo, Il Duomo di Monreale, written by professor Michele Amari, Monsignor Isidoro Carini, and Saverio Cavallaro. The book won an award at the 1873 Universal Exposition of Vienna, and in 1878, at the Exposizione Universale of Paris, and at other artistic and industrial expositions in Palermo. In 1877, the Ministry of Agriculture and Commerce lobbied the King to name him a knight in the Order of the Crown of Italy, for his work at the Palatine Chapel.
He also produced chromolithography tables for the Ministry of Education with depictions of the plants of Sicily, and the topography, and the archeological sites of Syracuse. His son, Amedeo John Engel Terzi, was best known for his detailed engravings of Diptera (flies).
