A pimiento (Spanish pronunciation: [piˈmjento]), pimento, or cherry pepper is a variety of large, red, heart-shaped chili pepper (Capsicum annuum) that measures 3 to 4 in (7 to 10 cm) long and 2 to 3 in (5 to 7 cm) wide (medium, elongate).

The flesh of the pimiento is sweet, succulent, and more aromatic than that of the red bell pepper. Some varieties of the pimiento type are hot, including the Floral Gem and Santa Fe Grande varieties. The fruits are typically used fresh or pickled. The pimiento has one of the lowest Scoville scale ratings of any chili pepper.
