Camp Liberty is a former installation of the United States Department of Defense in Baghdad, Iraq. The installation was used from 2012 to September 2016 to house members of the People's Mujahedin of Iran, who had been forcibly evicted from Camp Ashraf.

The People's Mojahedin Organization of Iran (PMOI), also known as Mojahedin-e-Khalq (MEK) or Mojahedin-e-Khalq Organization (MKO), is an Iranian dissident organization that was previously armed but has now transitioned primarily into a political advocacy group. Its headquarters are currently in Albania. The group's ideology is rooted in "Islam with revolutionary Marxism," but after the Iranian Revolution became about overthrowing the Government of the Islamic Republic of Iran and installing its own government. At one point the MEK was Iran's "largest and most active armed dissident group," and it is still sometimes presented by Western political backers as a major Iranian opposition group, but it is also deeply unpopular today within Iran, largely due to its siding with Iraq in the Iran–Iraq War.
