The Sudan People's Liberation Movement–North, or SPLM–N, is a political party and militant organisation in the Republic of the Sudan, based in the states of Blue Nile and South Kordofan. The group's armed forces are formally known as the Sudan People's Liberation Army–North or SPLA–N. In 2011 when South Sudan broke away from Sudan to form a new country, most of the Sudan People's Liberation Movement (SPLM) and Army (SPLA) left with it, leaving units remaining across the border in Sudan to form the SPLA–N.
