Chocolate liqueur is a liqueur with a principal flavor of chocolate.

There are several brands of chocolate liqueur on the market, attributed to a 1990s "chocolate craze." Although one food writer implies that chocolate liqueurs are new, chocolate liqueur is not a new invention. There is mention, in French, of producing and selling chocolate en liqueur as early as 1666. Context suggests this is a chocolate liqueur, not a chocolate liquor or other chocolate beverage. In New England prior to the 18th century American Revolution, a "chocolate wine" was popular. Its ingredients included sherry, port, chocolate, and sugar. A French manual published in 1780 also describes chocolate liqueur. An 1803 French pharmacy manual includes a recipe for a chocolate liqueur (ratafia de chocolat, also ratafia de cacao). An early 19th century American cookbook, published in 1825 and preserved in an historical archive in South Carolina, includes a similar recipe. Throughout the 19th century and into the early 20th century, manuals and encyclopedias in French, English, and Spanish give similar recipes. A late 19th century food science manual gives a recipe that includes techniques for clarifying and coloring the liqueur. A similar early 20th century manual gives four recipes.
