Ducana is a dessert dish that is popular on the Caribbean islands of Antigua, Montserrat and St. Vincent and the Grenadines. The dish is a type of dumpling made with coconut and sweet potatoes, often cooked in banana leaves. It is usually served with stewed or salted fish, and is a common staple food for many locals that enjoy the contrast of sweet and savory flavors.

Some say that the sweet potato is best used in the preparation of ducana, as the islands are brimming with sweet potatoes that were cultivated by the Arawak Indians a long time ago. Ducana can also be consumed cold, or thinly sliced and lightly fried as a snack.

A must-have for both the tourists and the locals, the dish is often made on Good Friday, when the islanders traditionally avoid meat.
