Cîroc (French pronunciation: [siʀɔk]) is a brand of alcoholic beverages produced in France since 2003 and owned by the British multinational alcoholic beverage company Diageo. The brand line includes vodka, flavored vodka-based products, and brandy.

Beginning in 2007, the marketing and promotion of Cîroc in the United States were conducted in partnership with rapper Sean Combs through an "equal-share venture," with profits from the brand split between Combs and Diageo. This arrangement was terminated in 2024 following Combs' legal dispute, leaving Diageo as the sole owner.

The name "Cîroc" is a portmanteau of the French word cime, meaning peak or summit-top, and roche, meaning rock, a reference to the high-altitude vineyards of the Gaillac region where Mauzac grapes are grown. The 'î' in the Cîroc logo is the i-circumflex letter used in the French language.

Cîroc's vodka is distinguished from nearly all other vodkas by being derived from grapes, rather than using grain, potatoes, or maize (corn). It is distilled to a very high level of alcohol by volume (ABV) concentration – about 96% (roughly the practical limit of ordinary distillation practices due to the ethanol and water becoming an azeotrope mixture) and is not aged or flavored before being diluted with water to 40% ABV (80 U.S. proof) for bottling, and thus fulfills the criteria for labeling as vodka (which in the United States requires at least 95% distillation concentration and 40% ABV bottling concentration for vodka).

The producer of Cîroc emphasizes its being distilled five times. The first four distillations use column stills and the final distillation is performed in a traditional copper pot still at the Distillerie de Chevanceaux.

Since 2010, the Cîroc brand has included a family of flavored drinks containing vodka. In the United States, these flavored beverages are bottled at 70 U.S. proof (35% ABV) – a lower ABV level than (unflavored) vodka, although much higher than that of a typical mixed drink. In the United States, the labels of these products say "made with vodka" rather than simply "vodka", although they are referred to as vodkas on the company website.

The brand introduced two flavored varieties to the market in 2010: Red Berry and Coconut. In 2011, the company added a Peach flavor. In May 2013, Cîroc and Sean Combs announced that a new flavor would be released called Cîroc Amaretto. On 15 July 2014, Combs announced via his Instagram page that Cîroc Pineapple would be the next flavor. In 2015, he announced a green apple flavor, in 2016 DJ Khaled was signed as another brand ambassador co-promoting a new mango flavor, and in 2017 Combs announced a French vanilla flavor to be produced in partnership with hip-hop artist French Montana. As of October 2021, the U.S. brand offerings include seven main-line flavor varieties: Mango, Apple, Pineapple, Red Berry, Coconut, Peach, and French Vanilla, and four "limited edition" varieties: White Grape, Summer Citrus, Summer Watermelon, and Pomegranate. In April 2022 Ciroc introduce one more flavor as CÎROC PASSION.

Cîroc VS Brandy, bottled at 80 U.S. proof (40% ABV), was added to the brand family in June 2018. It is a blend of aged French brandies, some of which is distilled in copper pot stills and aged in French oak. A review in The Spirits Business said its taste profile has "'rich' notes of fresh fruit, vanilla and a hint of French oak". In brandy production, "VS" is an abbreviation for "very special" and typically refers to a blend in which the youngest brandy has been aged for at least two years in a cask.
