Corn, also known as maize, is a grain plant cultivated for food. The origin of this grain remains unknown, however, many historians believe that corn was first domesticated in Mexico's Tehuacan Valley. Types of corn include sweet corn, popcorn, pod corn, flint corn, flour corn, waxy corn and dent corn.

Corn is one of the most important crops in the United States. Over the last years, the country's corn farmers experienced constant increases in annual revenues. In 2022/23, the U.S. was responsible for almost one-third of the global corn production.

In 2022/23, the United States exported around 42.5 million metric tons of corn, making the nation the world's second largest corn exporter. Mexico and China were the leading buyers of U.S. corn in 2022, purchasing approximately 662 million bushels and 579 million bushels respectively.
