Rum and Coke, or the Cuba libre, is a highball cocktail consisting of cola, rum, and in many recipes lime juice on ice. Traditionally, the cola ingredient is Coca-Cola ("Coke") and the alcohol is a light rum such as Bacardi; however, the drink may be made with various types of rums and cola brands, and lime juice may or may not be included.

Rum is a liquor made by fermenting and then distilling sugarcane molasses or sugarcane juice. The distillate, a clear liquid, is often aged in barrels of oak. Rum originated in the Caribbean in the 17th century, but today it is produced in nearly every major sugar-producing region of the world, such as the Philippines, where Tanduay Distillers, the largest producer of rum worldwide, has its headquarters.
