Given the United States' large size it has numerous regional variations. The United States' regional cuisine is characterized by its extreme diversity and style with each region having its own distinctive cuisine.

The cuisine has a history dating back before the colonial period when the Native Americans had a rich and diverse cooking style for an equally diverse amount of ingredients. With European colonization, the style of cookery changed vastly, with numerous ingredients introduced from Europe, as well as cooking styles and modern cookbooks. The style of cookery continued to expand into the 19th and 20th centuries with the influx of immigrants from various nations across the world. This influx has created a rich diversity and a unique regional character throughout the country. In addition to cookery, cheese and wine play an important role in the cuisine. The wine industry is regulated by American Viticultural Areas (AVA) (regulated appellation), entirely unlike laws found in countries such as France and Italy.
