Illycaffè S.p.A. (branded and stylised as illy) is an Italian coffee company specializing in espresso, headquartered in Trieste. Illy markets its coffee globally in silver and red pressurized, oxygen-free cans; operates a network of cafes on shopping streets, in museums, and in airports; and, since 2009, has marketed a line of coffee-flavored energy drinks as illy issimo.

Either as whole beans or ground coffee, Illy offers medium, dark, and decaffeinated roast variations; as well as single-origin arabica variations, as available; each from Brazil, Guatemala, Ethiopia, Colombia, Costa Rica, Nicaragua, Tanzania or India. Seasonally, the company offers Idillyum, a low-caffeine arabica grown in El Salvador. The company packages coffee as whole beans, pre-ground coffee, ESE pods, and iperEspresso capsules.

Illy was founded in 1933 by Francesco Illy, remains family-controlled and employs about 2700+ employees (2015). 2016 revenues totalled €460 million, and in late 2019, Illycaffee sought to expand into the United States market, offering a 20% stake in the company to potential investors.
