Vitis mustangensis, commonly known as the Mustang Grape, is a species of grape that is native to the southern United States. Its range includes western Louisiana, Texas, and Oklahoma. This woody species produces small clusters of hard green fruit that ripen into soft 3⁄4-inch (2 cm) dark purple berries in August-September. The fruit can be potentially irritating to the skin when picked or eaten, and are mildly unpleasant to eat because of its bitterness and high acidity content. They have a thick outer layer of flesh and on average contain four seeds. This variety of grape is recognized by the white velvet-like underside of the leaves, and often covers small trees, shrubs, fences and other objects that it grows near. 
The grape has a culinary use as jelly and grape juice, both of which are typically sweetened with sugar so as to be palatable. The fruit and leaves of Mustang Grapes may also be used to dye wool.
