Maiolino Bisaccioni (1582 – 8 June 1663) was an Italian mercenary and author of both novels and chronicles of contemporary history, mainly of events during the Thirty Years' Wars.

Maiolino was born in Ferrara, the son of Giralamo Bisaccioni and Lucia Trotti, who were both from prominent families in Jesi.

In 1603, he was back in Italy where he engaged in another duel with Alessandro Gonzaga, his commander, and this led to his expulsion from the Papal States.

His most important novel, Il Demetrio moscovita (1639), recounts False Dmitry I's rise to power and tragic death.

Between 1637 and 1664 he published four collections of short stories: La nave, L'albergo, L'isola, and Il porto.
