All U.S., Canadian, U.K., Australian, and New Zealand citizens, even infants, need a valid passport to enter Italy for stays of up to 90 days. Visas are not required for stays under 90 days.
Before your trip, make two copies of your passport's data page (one for someone at home and another for you to carry separately). Or scan the page and email it to someone at home and/or yourself.
