Maslak is one of the main business districts of Sarıyer, Istanbul, Turkey, located on the European side of the city. It was formerly an exclave of the municipality of Şişli, though being far north and actually closer to the municipalities of Sarıyer and Beşiktaş. Therefore, a legislation was approved by the Interior Commission of the Turkish Parliament on October 18, 2012, that shifted the jurisdiction of the Maslak district from Şişli to Sarıyer.
