A pumpkin is a squash fruit, usually orange in color when ripe (although there are also white, red, and gray varieties). Pumpkins grow as a gourd from a trailing vine of certain species in the genus Cucurbita. Cultivated in North America, continental Europe, Australia, New Zealand, India and some other countries, Cucurbita species referred to as pumpkins include Curcurbita pepo, Cucurbita maxima, Cucurbita mixta, and Cucurbita moschata — all plants native to the Western hemisphere. The pumpkin varies greatly in form, being sometimes nearly globular, but more generally oblong or ovoid in shape. The rind is smooth and its color depends on the particular species (very dark-green, very pale-green, & orange-yellow are common). The larger kinds acquire a weight of 40 to 80 lb (18 to 36 kg) but smaller varieties are in vogue for garden culture. Pumpkins are a popular food, with their insides commonly eaten cooked and served in dishes such as pumpkin pie; the seeds can be roasted as a snack. Pumpkins are traditionally used to carve Jack-o'-lanterns for use in Halloween celebrations.

Botanically it is a fruit, referring to a plant part which grows from a flower; however, it is widely regarded as a vegetable in culinary terms, referring to how it is eaten.

Butternut squash is called "butternut pumpkin" in Australia, and "neck pumpkin" in parts of Pennsylvania, where it is commonly regarded as a pumpkin and used in similar ways to other pumpkin.
