Italian-American cuisine is a style of Italian cuisine adapted throughout the United States. Italian-American food has been shaped throughout history by various waves of immigrants and their descendants, called Italian Americans.

Italian cuisine is a Mediterranean cuisine consisting of the ingredients, recipes and cooking techniques developed in Italy since Roman times and later spread around the world together with waves of Italian diaspora. Some of these foods were imported from other cultures. Significant changes occurred with the colonization of the Americas and the introduction of potatoes, tomatoes, capsicums, maize and sugar beet—the latter introduced in quantity in the 18th century. It is one of the best-known and most appreciated gastronomies worldwide.
