Kuat () is a brand of guarana beverage sold by The Coca-Cola Company in Brazil. Kuat was introduced in Brazil in 1997 to compete with the leading guarana beverage, Guaraná Antarctica, which was stealing market share from Coca-Cola's cola products.
In Brazil, Kuat is available in a diet version (Kuat Zero) and a green-tea infused version (Kuat Eko).
Kuat was briefly sold in Norway starting in 2003 under the name SanSão.
In 2002, Coca-Cola announced plans to test market Kuat in the United States.
