Aloisio Gonzaga (20 April 1494 – 19 July 1549) was an Italian condottiero.

He was the sixth son of another condottiero, Rodolfo Gonzaga and his wife Caterina Pico.

The lord of Castel Goffredo, Castiglione and Solferino, he was the founder of two cadet branches of the House of Gonzaga known as the "Castel Goffredo, Castiglione and Solferino Gonzagas" and "Castel Goffredo Gonzagas";[1][2] both branches went extinct in 1593.

He was one of the most important figures in the history of Castel Goffredo.

He made it capital of his small Marquisate of Castel Goffredo[3][4] and produced most of its town planning.
