Koukouli (Greek: Κουκούλι) is a village of the Zagori region, in the municipal unit of Tymfi, in northwestern Greece.

The village takes its name from the Greek word of silkworm cocoon; silk production in the wider region of Zagori was popular during the past centuries.

The privileges which were granted to the federation of Zagori and which are due, in the biggest part, to the influence of notable Zagorians over the Sublime Porte, were preserved until 1868.

Alexios Plakidas, a local benefactor, donated huge amounts of money for the village and the Zagori region.

Prior to the Second World War, Koukoulians used to migrate to Asia Minor and the United States.
