Muhammad Naeem Noor Khan (Urdu: محمد نعيم نور خان, born 1979) is an alleged Al-Qaeda operative and computer expert. Arrested in Pakistan on 13 July 2004, files found on his laptop contained details of a terrorist plot to attack U.S. financial buildings and locations in the UK, including Heathrow Airport. Khan's arrest was attributed to leads arising from the arrest of Musaad Aruchi a month earlier. Following his arrest, Khan agreed to cooperate with investigators, and continued to communicate with Al-Qaeda as part of a sting operation. Following the publication of Khan's name, British authorities moved quickly to arrest 13 members of the British terrorist cell with which Khan had been communicating (the so-called Luton cell). Evidence gathering may not have yet been completed and other plotters may have escaped due to the need to make the arrests quickly.

Conversely, on 8 August 2004 on CNN's Late Edition with Wolf Blitzer, National Security Advisor Condoleezza Rice told Wolf Blitzer that Khan's name had been revealed "on background" (an expression with no fixed meaning in journalism, but which is often understood to mean that the information may not be published, or at least that the source may not be revealed); afterwards, however, when the transcript of the background briefing revealed that Khan had not in fact been identified by name, Rice's office retracted the statement. Sean McCormack, a National Security Council spokesman, stated "She was in the middle of making a point and [Blitzer] interrupted her, and she reflexively repeated 'on background,' but she was not confirming it and went on to complete her thought." Precisely who leaked Khan's name, and why, was controversial. Critics of the Bush administration accused them of damaging national security by the deliberate "outing" of an undercover
