Courvoisier is a brand of cognac, a type of French brandy made from grapes, with production based in the town of Jarnac in the Charente region of France. It is the youngest and smallest of the "big four" cognac houses, which also include Hennessy, Martell, and Rémy Martin. Courvoisier is the only cognac producer that controls every step of its production process but does not do any distilling of its own. Instead, it changes the process for different vintages and regional variations in eaux-de-vie, and has never owned vines. Courvoisier cognac is aged in barrels handmade from 200-year-old oak sourced from the Tronçais forest in France.

Courvoisier is run from the original Château Felix Courvoisier and Jules Gallois moved to in 1828. Today, the Courvoisier Château has a boutique and museum, offering private tastings and exclusive tours. The museum features several items linked to Napoleon I. Courvoisier was the first cognac brand to appear on TV with an advertisement on UK television broadcast to nine million viewers. In 2009, Courvoisier was the first alcohol brand to release a 3D advertisement, titled "Cognac With Another Dimension", on TV and in cinemas, ahead of the viewing of the biggest-grossing film of all time, Avatar.

Courvoisier offers a range of cognacs, including Courvoisier VS, which is an authentic and joyous introduction to the Courvoisier collection. The Courvoisier VSOP and Rose Liqueur are also very popular. The last blend to be developed and launched by the fifth Chief Blender, Jean-Marc Olivier, in conjunction with the sixth Chief Blender Patrice Pinet, LEssence de Courvoisier is a sublime harmony of over 100 rare eaux-de-vie from the last 100 years, each championed as the most innovative of their time.
