Gaetano Gandolfi (31 August 1734 – 20 June 1802) was an Italian painter of the late Baroque and early Neoclassic period, active in Bologna.
Gaetano was born in San Matteo della Decima, near Bologna, to a family of artists. Ubaldo Gandolfi was his brother, Mauro Gandolfi was his son, and Democrito Gandolfi was his grandson. Gaetano became a "student" at the Accademia Clementina in Bologna, where he was taught by Felice Torelli and Ercole Lelli. In the academy, he was the recipient of several prizes for both figure drawing and sculpture. Later, in an autobiography, Gaetano claimed Felice Torelli (1667–1748) as his master. Other sources mention Ercole Graziani the Younger (1688–1765) and Ercole Lelli. He traveled to England, and became strongly influenced by Tiepolo. Gaetano died in Bologna, Italy.
