Eminönü, historically known as Pérama, is a predominantly commercial waterfront area of Istanbul within the Fatih district near the confluence of the Golden Horn with the southern entrance of the Bosphorus strait and the Sea of Marmara. It is located in the part of Istanbul known as the historical peninsula, connected to Karaköy via the Galata Bridge across the Golden Horn. It was administered as part of the Sultanahmet district from 1928 to 2009 when Sultanahmet was absorbed into Fatih. Eminönü, which was a district municipality until March 7, 2008, was abolished on this date and connected to Fatih district by law. It is completely located within the city wall, the historical core of the city, and forms one of the most vibrant areas of the central area.

Fatih is a municipality and district of Istanbul Province, Turkey. Its area is 15 km2, and its population is 368,227 (2022). It is home to almost all of the provincial authorities but not the courthouse. It encompasses the historical peninsula, coinciding with old Constantinople. In 2009, the district of Eminönü, which had been a separate municipality located at the tip of the peninsula, was once again remerged into Fatih because of its small population. Fatih is bordered by the Golden Horn to the north and the Sea of Marmara to the south, while the Western border is demarked by the Theodosian wall and the east by the Bosphorus Strait.
