Cağaloğlu is a neighbourhood located in the Fatih district of Istanbul, Turkey. Much of the publishing industry in Istanbul is located in Cağaloğlu. It is also famous for its ancient hamam, or Turkish bath, known as the Cağaloğlu Hamam.
The neighbourhood gets its name from Cigalazade Yusuf Sinan Pasha (Turkish: Cağaloğlu Yusuf Sinan Paşa; c. 1545–1605), an Ottoman admiral and statesman of Genoese descent, as well as a member of the influential Cicala family of Genoa. The original name Cigalaoğlu (meaning "of the Cigala (Cicala) family", or literally "Cigala-son" as a Turkified surname) eventually turned into Cağaloğlu through the course of centuries.
