The Turkish Naval Forces (Turkish: Türk Deniz Kuvvetleri), or Turkish Navy (Turkish: Türk Donanması) is the naval warfare service branch of the Turkish Armed Forces.

The modern naval traditions and customs of the Turkish Navy can be traced back to 10 July 1920, when it was established as the Directorate of Naval Affairs during the Turkish War of Independence led by Mustafa Kemal Atatürk. Since July 1949, the service has been officially known as the Turkish Naval Forces.
