'Albanian village';[1][2] Greek: Μέγα Ρεύμα, romanized: Mega Revma) is a neighbourhood in the municipality and district of Beşiktaş, Istanbul Province, Turkey.

At the eastern end of Arnavutköy the coast juts out to form Akıntıburnu (the Cape of the Current) where the waters of the Bosphorus once flowed so powerfully that small boats had to be towed round it.

[1][6][2] In 1863, Robert College, the oldest American school outside the United States, was established on its current campus which originally stretched from Arnavutköy to the vicinity of Bebek and Rumelihisarı.

According to the Salname for 1912, the district's total population was 7,482, consisting ethnographically of 5,973 Rûms (Christians), 493 Muslims, 342 Armenians, 32 Jews and 642 people of other nationality.

The waterfront at Arnavutköy is lined with some of the most picturesque late 19th and early 20th-century wooden houses to survive along the Bosphorus, many of them decorated in Art Nouveau style.
