Allspice, also known as Jamaica pepper, myrtle pepper, pimenta, or pimento, is the dried unripe berry of Pimenta dioica, a midcanopy tree native to the Greater Antilles, southern Mexico, and Central America, now cultivated in many warm parts of the world. The name "allspice" was coined as early as 1621 by the English, who valued it as a spice that combined the flavour of cinnamon, nutmeg, and clove.

Several unrelated fragrant shrubs are called "Carolina allspice" (Calycanthus floridus), "Japanese allspice" (Chimonanthus praecox), or "wild allspice" (Lindera benzoin). "Allspice" is also sometimes used to refer to the herb costmary.

Allspice is the dried fruit of the Pimenta dioica plant. The fruits are picked when green and unripe and are traditionally dried in the sun. When dry they are brown and resemble large, smooth peppercorns. Fresh leaves are similar in texture to bay leaves and similarly used in cooking. Leaves and wood are often used for smoking meats where allspice is a local crop.

Care must be taken during drying to ensure that volatile oil, such as eugenol, remains in the end products.
