Frappuccino is a trademarked line of blended coffee beverages sold by Starbucks. It consists of coffee blended with ice and various other ingredients, usually topped with whipped cream. Frappuccinos are also sold as bottled coffee beverages in stores and from vending machines.

Frappuccino is a portmanteau of frappé and cappuccino, an espresso coffee with frothed milk. It is unclear whether frappé is taken from frappé, a Greek iced coffee, or from the Boston area term for a thick milkshake frappé (pronounced "frap"), both of which come from the French word frappé. The original Frappuccino beverage was developed, named, trademarked and sold by George Howell's Eastern Massachusetts coffee shop chain, The Coffee Connection. When Starbucks purchased The Coffee Connection in 1994, they also gained the rights to use, make, market, and sell the Frappuccino beverage, and soon after began to sell the beverage chain-wide.

In response to the success of Frappuccinos, several Starbucks' competitors have developed similar drinks with similar sounding names, but only Starbucks can legally use the "Frappuccino" trademark. Similar frozen coffee drinks were served starting in 1988 by the Seattle chain Cinnabon under the names Mochalatta and Caramelatta.^{[citation needed]}Coffee Break is one.Gloria Jean's offers a similar frozen coffee drink but calls them Chillers.
