The Kinburn Peninsula (Ukrainian: Кінбурнський півострів, romanized: Kinburnskyi pivostriv, Russian: Кинбурнский полуостров, romanized: Kinburnskiy poluostrov, Turkish: Kılburun) is a peninsula in Southern Ukraine, which separates the Dnieper–Bug estuary from the Black Sea.

It is part of the Ivory Coast of Sviatoslav National Nature Park.

Since April 2022, the Kinburn Peninsula has been fully occupied by Russian forces.

Etymology comes from Turkish Kılburun, literally 'nose (land strip) [as subtle as a] hair'.

The Battle of Kinburn was fought on 17 October 1855 as part of the Crimean War.
