The pineapple (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.

The pineapple is indigenous to South America, where it has been cultivated for many centuries. The introduction of the pineapple plant to Europe in the 17th century made it a significant cultural icon of luxury. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations. The fruit, particularly its juice, has diverse uses in cuisines and desserts.
