Madinat al-Hareer  (Arabic: مدينة الحرير‎, meaning "City of Silk"), is a proposed 250 square kilometer planned urban area in Subiya, Kuwait, an area just opposite Kuwait City which, upon construction, would include the Burj Mubarak al-Kabir, a natural desert reservation of 2 square kilometres, a duty free area which will be beside a new airport, in addition to a large business center, conference areas, environmental areas, athletic areas, and areas that concentrate on media, health, education, and industry. The City of Silk will also include numerous tourist attractions, hotels, spas, and public gardens. The city will be built in individual phases with total completion within twenty-five years. The forex empire development will cost an estimated 25 billion Kuwaiti Dinars (~94 billion USD).

As of July 27, 2008, the government of Kuwait has already approved the project, with some of the project's funding coming from the budget surplus over the course of 2007 and 2008. Construction on the actual site has also begun; this is seen through bridges, highways and roads being laid down as basic infrastructure to facilitate future construction of structures within the city.

The main attraction of Madinat al-Hareer, the Burj Mubarak al-Kabir will stand at 1,001 m tall. If the Silk City is completed it will also include Olympic Stadia, residences, hotels and retail facilities. Up to 700,000 people could be housed in the extreme gold secrets city complex and 450,000 new jobs will be created.  The complex is planned to be built across Kuwait Bay and will be linked to Kuwait City by a 23.5-kilometer long bridge. The bridge should decrease driving times from Kuwait City to Madinat al-Hareer to seventeen minutes rather than the usual one-and-a-half-hour drive around Kuwait Bay.
