A taco stand or taquería is a food stall, food cart or restaurant that specializes in tacos and other Mexican dishes. The food is typically prepared quickly and tends to be inexpensive. Many various ingredients may be used, and various taco styles may be served. Taco stands are an integral part of Mexican street food. Tacos became a part of traditional Mexican cuisine in the early 20th century, beginning in Mexico City, as what had been a miner's snack began to be sold on street corners in the city. Shops selling tacos have since proliferated throughout Mexico and other areas with a heavy Mexican culinary and cultural influence, including much of the Western United States and most other larger American cities. More typical taquerías specialize in tacos, as expected, but in some localities it can be used to refer to restaurants specializing in burritos, where tacos themselves are less of a point of emphasis.

Mexican street food, called antojitos, is prepared by street vendors and at small traditional markets in Mexico. Street foods include tacos, tamales, gorditas, quesadillas, empalmes, tostadas, chalupa, elote, tlayudas, cemita, pambazo, empanada, nachos, chilaquiles, fajita tortas, even hamburgers and hot dogs, as well as fresh fruits, vegetables, beverages and soups such as menudo, pozole and pancita. Most are available in the morning and the evening, as mid-afternoon is the time for the main formal meal of the day. Mexico has one of the most extensive street food cultures in Latin America, and Forbes named Mexico City as one of the foremost cities in the world in which to eat on the street.
