Kayhan (Persian: کيهان, lit. 'The Cosmos') is a Persian-language newspaper published in Tehran, Iran. It is considered "the most conservative and hard-line Iranian newspaper." Hossein Shariatmadari is the editor-in-chief of Kayhan. According to the report of the New York Times in 2007, his official position is representative of the Supreme Leader of Iran.
Kayhan has about 1,000 employees worldwide. There are conflicting reports about its circulation numbers: in 2006 the BBC gave it as 60,000–100,000 copies, in 2007 the New York Times gave "about 70,000", and in 2008 a New York University School of Law journal article reported it as 350,000 copies. Kayhan also publishes special foreign editions, which include the English-language Kayhan International.
