Ioannis Pesmazoglou (Greek: Ιωάννης Πεσμαζόγλου; 1857–1906) was a Greek banker, economist and politician. Ioannis Pesmazoglou was from Constantinople (now Istanbul), although his family originate from Enderlik, in Cappadocia. Pesmazoglou studied economic sciences in Paris and in the beginning, he was employed at the Crédit Lyonnais bank in Alexandria, Egypt. In 1882, he became head of the Anglo-Egyptian Bank, before returning to Athens, where he founded his own bank. In 1897, Pesmazoglou's bank was merged with the Bank of Athens, of which he now became chairman. Pesmazoglou remained a member of the board of the Bank of Athens until his death.
