Tofu skin, yuba, beancurd skin, beancurd sheet, or beancurd robes is a food item made from soybeans. During the boiling of soy milk, in an open shallow pan, a film or skin composed primarily of a soy protein-lipid complex forms on the liquid surface. The films are collected and dried into yellowish sheets known as tofu skin. Since tofu skin is not produced using a coagulant, it is not technically a proper tofu; however, it does have a similar texture and flavor to some tofu products.

Tofu skin's use was first documented in written records in China in the sixteenth century. It is widely used, fresh, fermented, or dried, in Chinese, Korean, and Japanese cuisine.
