Piali Pasha, (Turkish: Piyale Paşa) (c. 1515–1578) was an Ottoman admiral (Kapudan Pasha) between 1553 and 1567 and a Vizier after 1568. He is also known as Piale Pasha in English.
Born in Viganj on the Pelješac peninsula, he was of Croatian origin. He was captured in the 1526 Battle of Mohács and became an Ottoman soldier under Turgut Reis.
Piyale Pasha received his formal education at the Enderun School (Imperial Academy) in Constantinople (modern-day Istanbul), Ottoman Empire. He graduated from the Enderun with the title of Kapıcıbaşı and was appointed Sanjak Bey (Province Governor) of Gallipoli.
He was promoted to Bahriye Beylerbeyi (i.e. First Lord of Admiralty) and became Admiral-in-Chief of the Ottoman Fleet at the age of 39.
In 1554 he captured the islands of Elba and Corsica with a large fleet which included famous Ottoman admirals like Turgut Reis and Salih Reis. The following year Sultan Suleiman the Magnificent assigned him with the task of helping France against the Spaniards upon request by the mother of King Francis II, and Piyale Pasha set sail on 26 June 1555. The Ottoman fleet met the French fleet at Piombino and successfully repulsed a Spanish attack on France while conquering several Spanish fortresses on the Mediterranean Sea.
In June 1558, joined by Turgut Reis, Piyale Pasha sailed to the Strait of Messina and the two admirals captured Reggio Calabria. From there, they went to the Aeolian Islands and captured several of them, before landing at Amalfi, the Gulf of Salerno, and capturing Massa Lubrense, Cantone and Sorrento. They later landed at Torre del Greco, the coasts of Tuscany, and Piombino. In September 1558 they assaulted the coasts of Spain before capturing Minorca and inflicting particular damage on the island's ports.
