Butternut squash (a variety of Cucurbita moschata), known in Australia and New Zealand as butternut pumpkin or gramma, is a type of winter squash that grows on a vine. It has a sweet, nutty taste similar to that of a pumpkin. It has tan-yellow skin and orange fleshy pulp with a compartment of seeds in the blossom end. When ripening, the flesh turns increasingly deep orange due to its rich content of beta-carotene, a provitamin A compound.

Although botanically a fruit (specifically, a berry), butternut squash is used culinarily as a vegetable that can be roasted, sautéed, puréed for soups such as squash soup, or mashed to be used in casseroles, breads, muffins, and pies. It is part of the same squash family as ponca, waltham, pumpkin, and calabaza.
