The pineapple (Ananas comosus) is a tropical plant with edible multiple fruit consisting of coalesced berries, and the most economically significant plant in the Bromeliaceae family.

Pineapples may be cultivated from a crown cutting of the fruit, possibly flowering in 20–24 months and fruiting in the following six months.Pineapple does not ripen significantly post-harvest.

Pineapples can be consumed fresh, cooked, juiced, and preserved. They are found in a wide array of cuisines. In addition to consumption, the pineapple leaves are used to produce the textile fiber piña in the Philippines, commonly used as the material for the men's Barong Tagalog and women's Baro't saya formal wear in the country. The fiber is also used as a component for wallpaper and other furnishings.
