Kish (Persian: کیش listen), is a 91.5-square-kilometre (35.3 sq mi) resort island in Bandar Lengeh County, Hormozgan Province, off the southern coast of Iran in the Persian Gulf. The island constitutes the city of Kish. Owing to its free trade zone status, the island is marketed as a consumer's paradise, offering shopping centers, tourist attractions, and resort hotels. It has an estimated population of around 40,000 residents and about 12 million visitors annually.

Kish Island has been mentioned in history variously as Kamtina, Arakia (Ancient Greek: Αρακία), Arakata, and Ghiss.

In 325 BC, Alexander the Great commissioned Nearchus to set off on an expeditionary voyage to the Sea of Oman and the Persian Gulf. Nearchus's writings on Arakata contain the first known mention of Kish Island in antiquity. When Marco Polo visited the Imperial court in China, he commented on the Emperor's wife's pearls; he was told that they were from Kish.

Kish is located in the Persian Gulf, 19 km (12 mi) from mainland Iran, and has an area of approximately 91 km (35 sq mi) with an outer boundary of 40 km (25 mi) and a nearly elliptical shape.

Kish is located on a narrow strip of tropical vegetation in the Northern Hemisphere, with the Persian plateau to the north and the Arabian Peninsula to the south.

Kish has a very dry semi-equatorial climate. Over an 8-year span, the median annual rainfall in Kish was 145 mm (5.7 in) (54% in winter, 28% in autumn, and 14% in summer) and the median annual temperature was 26.6 °C (79.9 °F). The relative atmospheric humidity in Kish makes it like a sea island except in cold seasons. The humidity is approximately 60% for most of the year. In the months from October to April, Kish's weather is mild, ranging from 18 °C (64 °F) to 25 °C (77 °F). The statistical data in the Kish free zone's archives shows that the island's temperature varies from very hot to moderately hot, accompanied by relatively high humidity, often interspersed by heavy rains of short durations in certain seasons. With the exception of some southeastern coastal areas and a few other islands in the Persian Gulf, Kish Island has the most sunny hours in the region, roughly 3,100 hours per year. Based on climatological classification and general weather conditions, Kish's proximity to the Tropic of Cancer and its exposure to high tropical pressure systems, as well as its position amidst hot and shallow waters, means the island tends to be hot and humid most of the year.

The Greek Ship is the wreck of a 1943 cargo steamship, the Koula F, on a beach on Kish's southwest coast. She was originally a British ship, Empire Trumpet, and was built in Scotland. In 1966, she ran aground and all attempts to salvage her failed.

Since the mid-1990s, the Iranian government has embarked on an aggressive campaign to position Kish as a rival to Dubai and to Doha. The campaign has included massive construction projects and programs designed to attract foreign investment and trade. Within the area of the Kish Free Zone, as it is known, the standard laws of the Islamic Republic of Iran are far more relaxed than on the mainland. This has resulted in more domestic tourism and international trade on the island. Kish's population includes both Muslims and Christians. In 2009, the total foreign trade of the Kish Free Zone was approximately $9.2 billion per annum. Fifteen percent of all imports to Iran are through Kish.

Investment incentives in the Kish free trade zone include:

• 15 years tax-exemption;
• no entry visa requirement;
• 100% foreign ownership possible;
• flexible monetary & banking services;
• extended legal guarantees & protection.

Besides the existing Iranian Oil Bourse, a new exchange, the Kish Stock Exchange was inaugurated in 2010 to facilitate foreign investment and monetary activities.
