The Kapudan Pasha (Ottoman Turkish: قپودان پاشا, Modern Turkish: Kaptan Paşa), also known in Turkish as Kaptan-ı Derya ("Captain of the Seas"), was the commander-in-chief of the navy of the Ottoman Empire. Around 160 captains served between the establishment of the post under Bayezid I and the office's replacement by the more modern Ottoman Ministry of the Navy (Bahriye Nazırlığı) during the Tanzimat reforms.
