Tito Lessi (8 January 1858 – 17 February 1917) was an Italian painter of historical subjects.
He was born in Florence and studied at the Florentine Academy of Fine Arts, under Enrico Pollastrini and Antonio Ciseri.
It was there that he became interested in history paintings, which was considered especially prestigious, due to the difficulties involved in assuring their accuracy.
After returning to Florence, he began repeating favorite subjects, often making several copies of each, which were mostly sold in France and Germany.
For the publisher Alinari of Florence, he made a hundred illustrations for their deluxe edition of the Decameron by Giovanni Boccaccio.
