Taganrog Bay (Russian: Таганрогский залив; Ukrainian: Таганрозька затока) is the northeastern arm of the Sea of Azov.
Three other rivers, the Kalmius, Mius and the Yeya, flow into the bay.
The flow of water into the bay is the chief factor for current development in the Sea of Azov.
It abounds in sandy spits that partly enclose shallow bays.
The major ports are Taganrog, Mariupol (Ukraine), and Yeysk.
