Istanbul Sapphire, or Sapphire, is a skyscraper located in the central business district of Levent in Istanbul, Turkey.

It was Istanbul's and Turkey's tallest skyscraper between 2010 and 2016, and the 4th tallest building in Europe when its construction was completed in 2010.[3] Sapphire rises 54 floors above ground level, and has an above-ground roof height of 238 meters: the building has an overall structural height of 261 meters including its spire, which is part of the design and not a radio antenna.[3] Designed by Tabanlıoğlu Architects, it is a shopping and luxury residence mixed-use development managed by Kiler GYO.[3] It is also the country's first ecological skyscraper.

As of 2019, Istanbul Sapphire is the 4th tallest skyscraper in Istanbul and Turkey, behind Metropol Istanbul Tower 1[4][5][6][7] (70 floors / 301 metres including its twin spires) in the Ataşehir district on the Asian side of the city; and the Skyland Istanbul Towers 1 and 2[8][9] (2 x 70 floors / 293 metres), located adjacent to Türk Telekom Stadium in the Seyrantepe quarter of the Sarıyer district, on the European side.

There are special floors with private gardens between every 3 floors, and every 9 floors are separated from each other by a communal living area or mechanical floors.[3] Design of the gardens are proposed with a number of alternatives and the consistency of garden maintenance is under the residence management company’s responsibility.
