A pear is a pomaceous fruit produced by a tree of genus Pyrus. The English word pear is probably from Common West Germanic *pera, probably a loanword of Vulgar Latin pira, the plural of pirum, which is itself of unknown origin. See also Peorð. The place name Perry can indicate the historical presence of pear trees. The term "pyriform" is sometimes used to describe something which is "pear-shaped".

The pear is classified within Maloideae, a subfamily within Rosaceae. The apple (Malus ×domestica) which it resembles in floral structure, is also a member of this subfamily. In both cases the so-called fruit is composed of the receptacle or upper end of the flower-stalk (the so-called calyx tube) greatly dilated, and enclosing within its cellular flesh the five cartilaginous carpels which constitute the "core" and are really the true fruit. From the upper rim of the receptacle are given off the five sepals, the five petals, and the very numerous stamens. Another major relative of the pear (and thus the apple) is the quince.

The form of the pear and of the apple respectively, although usually characteristic enough, is not by itself sufficient to distinguish them, for there are pears which cannot by form alone be distinguished from apples, and apples which cannot by superficial appearance be recognized from pears. A major distinction is the occurrence in the tissue of the fruit, or beneath the rind, of clusters of lignified cells known as "grit" in the case of the pear, while in the apple no such formation of woody cells takes place. The appearance of the tree—the bark, the foliage, the type of inflorescence (i.e. form of the flower cluster)—is, however, usually quite characteristic in the two species.
