The Istanbul Cevahir Shopping and Entertainment Centre (Turkish: İstanbul Cevahir Alışveriş Merkezi), also known as the Şişli Culture and Trade Centre (Şişli Kültür ve Ticaret Merkezi), is a modern shopping mall located on the Büyükdere Avenue in the Şişli district of Istanbul, Turkey. Opened on 15 October 2005, Istanbul Cevahir was the largest shopping mall in Europe in terms of gross leasable area between 2005 and 2011, and is one of the largest in the world.

The architectural design was begun by Minori Yamasaki, who died in 1986, and carried on by Turkish British architect Can Yavuzarslan.

Istanbul Cevahir was built on a 62,475 m (672,000 sq ft) land plot at a cost of US$250 million.

The complex has a total floor area of 420,000 m (4,521,000 sq ft) and a gross leasable area of 110,000 m (1,184,000 sq ft) for shops and restaurants.

The six retail floors of the shopping centre house 343 shops (some of which are the first in Turkey to sell certain international brands); 34 fast food restaurants and 14 full-service restaurants.

Other facilities include a large stage for shows and other events, the eleven-screen Paribu Cineverse Cevahir multicinema with c.2,400 seats, a bowling alley, a small roller coaster and several other entertainment facilities.

The building's 2,500 m (26,910 sq ft) glass roof carries the second biggest clock in the world, with three-metre (10-foot) high digits.

The four-story, 71,000-square-metre (764,000-square-foot) car park has space for 2,500 cars.
