Maize (/ˈmz/ MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taíno mahiz), also known as corn, is a large grain plant first domesticated by indigenous peoples in Mexico about 10,000 years ago. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn.

The leafy stalk of the plant produces separate pollen and ovuliferous inflorescences or ears, which are fruits, yielding kernels (often erroneously called seeds). Maize kernels are often used in cooking as a starch.

Most historians believe maize was domesticated in the Tehuacan Valley of Mexico. Recent research modified this view somewhat; scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication.

The Olmec and Mayans cultivated maize in numerous varieties throughout Mesoamerica, cooked, ground or processed through nixtamalization. It's believed that beginning about 2500 BC, the crop spread through much of the Americas. The region developed a trade network based on surplus and varieties of maize crops. Nevertheless, recent data indicates that the spread of maize took place even earlier. According to Piperno,
