Kornat (pronounced [kɔ̌rnaːt]) is an island in the Croatian part of the Adriatic Sea, in central Dalmatia.

[1] It is part of the Kornati National Park, which is composed of a total of 89 islands, islets and rocks.

In the 19th century, the island was alternatively known as Insel Incoronata (in German) and Krunarski Otok (in Croatian).

In recent history, the island became infamous as the site of what became known as the "Kornat Tragedy" (Croatian: Kornatska tragedija), when a group of firefighters flown in as part of the 2007 coastal fires firefighting effort perished.

Twelve out of thirteen men who found themselves surrounded by fire were killed in the event, which was the biggest loss of lives in the history of Croatian firefighting.
