The Azadi Stadium (Persian) is Iran's national stadium and the largest in the country. The Azadi stadium officially has a capacity of 100,000 people [3][4] and was built to host the 1974 Asian Games. The stadium is part of the much larger Azadi Sports Complex, and is surrounded by a rowing river, football training pitches, a weightlifting complex, swimming facilities and indoor volleyball and futsal courts, among many other amenities. Azadi Stadium is the fourth biggest association football stadium in the world, third in Asia and first in the Middle East.

Azadi Stadium hosts most of Iran's national games, and is the home arena for Persepolis F.C. and Esteghlal F.C. in the Iran Pro League.

In 2002, the lower level of the stadium had seats installed, the pitch was replanted along with the installation of an underground heating system. Stadium management also plans to later install seats in the upper level of the stadium. The renovations were completed in 2003, reducing the capacity of the stadium to 100,000 (Originally 120,000 capacity) as the lower level of the stadium was refurnished with 35,000 seats. Despite its reduced capacity, Azadi Stadium has been filled over capacity at times such as the Iran-Japan World Cup 2006 qualification match in March 2005 which resulted in the deaths of seven people. In 2004 a large jumbotron television was added, replacing the original scoreboard. This giant screen with a total area of about 300 square meters and screen area of 104 square meters (20m by 7.5m) is one of the biggest in the world.

The stadium was originally called the Aryamehr Stadium in honor of the former Shah of Iran but then changed to Azadi Stadium after the Iranian Revolution; "Azadi" means freedom in Persian. The stadium is located in the West of Tehran, and is easily accessible for most people living in the city. Opposing teams often find it difficult to play their best game, when the stadium is full, as the noise level becomes very high. According to Goal.com, Azadi Stadium was voted most intimidating in Asia.

The stadium hosted two West Asian Football Federation Championship in 2004 and 2008. The stadium also hosted thos Asian Club Championship in 1999 and 2002 where the hosts Esteghlal and Persepolis finished second and third.
