Istanbul's first electoral district is one of three divisions of the Istanbul electoral district for the purpose of elections to Grand National Assembly of Turkey. It elects thirty-five members of parliament (deputies) to represent the district for a five-year term by the D'Hondt method, a party-list proportional representation system.

The district covers the entire Anatolian side of the Istanbul Province, on the east of the Bosphorus. Currently, one seat is vacant because of the death of Sırrı Süreyya Önder, Member of Parliament and Deputy Speaker of The Grand National Assembly from DEM Party.
