Mexican cuisine is known for its intense and varied flavors, colorful decoration, and the variety of spices that it has. Mexican gastronomy, in terms of diversity of appealing tastes and textures, is one of the richest in the world, rich in proteins, vitamins, and minerals, though some people unaccustomed to eating it characterize it as greasy and excessively spicy.

When Spanish conquistadores arrived in the Aztec capital Tenochtitlan (on the ruins of which Mexico City was built), they found that the local people's diet consisted of corn-based dishes with herbs, usually complemented with beans. Later on, the conquistadores added to the indigenous foods of pre-Columbian (including chocolate, maize, the tomato, and vanilla) the rice, beef, and wine that they brought with them from . The totopo (a deep-fried chip of corn tortilla) may have been created as part of this cuisine.

Most of today's Mexican cuisine is based on Native American traditions, including the Aztecs and Maya, combined with culinary trends introduced by Spanish colonists. Quesadillas, for example, are a flour or corn tortilla with cheese (often a Mexican-style soft farmer's cheese such as Queso Fresco), beef, chicken, pork, etc. The indigenous part of this and many other traditional foods is the chile pepper. Foods like these tend to be very colorful because of the rich variety of vegetables (among them red peppers, green peppers, chiles, broccoli, cauliflower, and radishes) and meats in Mexican food.

Major Dishes include:

Mexican food varies by region, because of local climate and geography and ethnic differences among the indigenous inhabitants and because these different populations were influenced by the Spaniards in varying degrees. The north of is known for its beef production and meat dishes; southeastern , on the other hand, is known for its spicy vegetable and chicken-based dishes. Veracruz-style is a common method of preparing seafood.

There are also more exotic dishes, cooked in the Aztec or Maya style, with ingredients ranging from iguana to rattlesnake, deer, spider monkey, and even some kinds of insects. This is usually known as comida prehispanica (or prehispanic food), and although not very common, is relatively well known.

Mexican cuisine has combined with the cuisine of the southwest to form Tex-Mex cuisine.  Another slight version of Mexican food is New Mexican Food, which can be found in, of course, New Mexico.
