Daiquiri, or daiquirí, is a family of cocktails whose main ingredients are rum and lime juice.

Originally the drink was served in a tall glass packed with cracked ice. A teaspoon of sugar was poured over the ice and the juice of one or two limes was squeezed over the sugar, with two or three ounces of rum after. Now they are most commonly mixed in a shaker with ice, and then strained into a chilled cocktail glass.

There are a wide variety of alcoholic mixed drinks made with finely pulverized ice are often called a "frozen daiquiri", but these are not true daiquiris.

There are several versions, but those that gained international fame are the ones made in the El Floridita bar in Havana, Cuba.

The daiquiri was one of the favorite drinks of writer Ernest Hemingway and president John F. Kennedy.
