Lattanzio Gambara (* 1530 in Brescia; 18. March 1574 ebenda) was an Italian painter and draughtsman of the Renaissance. Born the son of a tailor, he apprenticed to Giulio Campi, who accepted him in Cremona at the age of 15. From 1549 he worked together with his later father-in-law Girolamo Romanino in Brescia. He was mainly active as a church painter and fresco painter. In 1574 he died of the consequences of a fall from a scaffold.
