Chicken parmigiana, or chicken parmesan (Italian Pollo alla parmigiana) (also referred to colloquially in the United States as 'chicken parm' and in Australia as a 'parmy', 'parmi'or 'parma'), is a popular Italian-American dish. It consists of a breaded chicken breast topped with tomato sauce and mozzarella, parmesan or provolone cheese.

A slice of ham or bacon is sometimes added, but not all chefs are in agreement with the addition of pork. It has been speculated that the dish is based on a combination of the Italian melanzane alla Parmigiana, a dish using breaded eggplant slices instead of chicken, along with costelette Parmigiana (the latter generally served without sauce or cheese in Italy).

Chicken parmigiana is included as the base of a number of different meals, including sandwiches and pies, and the meal is used as the subject of eating contests at some restaurants.
