A cranberry juice and vodka cocktail over ice, garnished with a lime wedge is called a Cape Codder. Some people just call it vodka cranberry! Variations of this cocktail with ginger ale, club soda, grapefruit juice and other ingredients are all famous on their own. For example the famous Cosmopolitan drink has triple sec besides cranberry juice and vodka. Some more information on additional cocktails I found interesting is listed in this article from Wikipedia.
