Tourism attracted 2.3 million people to Iran in 2009 and 3.2 million in 2011.Iran plans to have 20 million tourists annually by 2025.

The landscape of Iran is diverse, providing a range of activities from hiking and skiing in the Alborz mountains, to beach holidays by the Persian Gulf and the Caspian Sea. Over the next five years a number of tourism-friendly infrastructure projects will be undertaken on the Persian Gulf island of Kish, which at present attracts around 1m visitors per year, the majority of whom are Iranian. In general, Iranians are warm, friendly and generous individuals with a strong interest in foreigners and other cultures.

Before the Iranian revolution and the subsequent Iran–Iraq War, tourism was characterized by significant numbers of visitors travelling to Iran for its diverse attractions, boasting cultural splendours and a diverse and beautiful landscape suitable for a range of activities. Tourism declined dramatically during the Iran–Iraq War in the 1980s.

Since the Iranian revolution in 1979, the majority of visitors to Iran have been religious pilgrims and businesspeople. Official figures do not distinguish between those travelling to Iran for business and those coming for pleasure, and they also include a large number of diaspora Iranians returning to visit their families in Iran or making pilgrimages to holy Shia sites near Mashhad and elsewhere. Domestic tourism in Iran is one of the largest in the world. Despite the international tensions, the government continues to project strong rises in visitor numbers and tourism revenue over the forecast period, and to talk of projects to build an additional 100 hotels, for example, to expand its currently limited stock.

Iran (ⁱ/ɪˈrɑːn/ or /aɪˈræn/;Persian: ایران‎ [ʔiˈɾɒn] ( listen)), officially the Islamic Republic of Iran (Persian: جمهوری اسلامی ایران‎ Jomhuri-ye Eslāmi-ye Irān), is a country in Southern and Western Asia. The name "Iran", which in Persian means "Land of the Aryans", has been in use natively since the Sassanian era. It came into use internationally in 1935, before which the country was known to the Western world as Persia ( /ˈpɜrʒə/ or /ˈpɜrʃə/). Both "Persia" and "Iran" are used interchangeably in cultural contexts; however, "Iran" is the name used officially in political contexts.

The 18th-largest country in the world in terms of area at 1,648,195 km² (636,372 sq mi), Iran has a population of around 79 million. It is a country of particular geopolitical significance owing to its location in the Middle East and central Eurasia. Iran is bordered on the north by Armenia, Azerbaijan and Turkmenistan. As Iran is a littoral state of the Caspian Sea, which is an inland sea, Kazakhstan and Russia are also Iran's direct neighbors to the north. Iran is bordered on the east by Afghanistan and Pakistan, on the south by the Persian Gulf and the Gulf of Oman, on the west by Iraq and on the northwest by Turkey. Tehran is the capital, the country's largest city and the political, cultural, commercial and industrial center of the nation. Iran is a regional power, and holds an important position in international energy security and world economy as a result of its large reserves of petroleum and natural gas. Iran has the second largest proven natural gas reserves in the world and the fourth largest proven petroleum reserves.
