Vitis vulpina (with common names frost grape, winter grape, fox grape, and wild grape) is a North American species of herbaceous perennial vines in the grape family. It is widespread across most of the eastern and central United States as well as the Canadian Province of Ontario.

The genus name Vitis comes from the Latin word for "vine" and the species name vulpina comes from the Latin word for "fox-like" or belonging to a fox. It is believed that foxes were attracted to this type of grapevine, and Linnaeus used the term vulpina to differentiate these smaller wild grapes from the other American known grapes. The more common name, frost grape, refers to the fact that this otherwise acidic/tart-tasting grape becomes more desirable and sweet once it is exposed to a frost. Vitis vulpina is a high-climbing woody vine with a thick trunk and red tendrils. The grapes and the vine itself have many uses ranging from herbal remedies to edible delicacies.
