Free Joseon (Korean: 자유조선), formerly known as Cheollima Civil Defense and formally styled as The Provisional Government of Free Joseon, is an anti-North Korea activist group established on 4 March 2017. It has been noted for protecting the family of Kim Jong Nam following his assassination in Malaysia. It is also known to support North Korean defectors. On 1 March 2019, "Cheollima Civil Defense" was renamed to "Free Joseon", which is also the proposed name for North Korea if it "overthrows its current government".
