Peter Par Jiek (1950s – 9 April 2017) was a brigadier general of the Sudan People's Liberation Army (SPLA), and veteran of the Second Sudanese Civil War. In the course of that conflict, Par fought under Riek Machar with several rebel and pro-government groups, and eventually became a powerful militia commander in Unity State. In that region, he established his own fiefdom and gained some notoriety for his rivalry with another rebel leader, Peter Gadet. Even though he had followed Machar during the whole Second Sudanese Civil War until 2005, Par sided with President Salva Kiir Mayardit upon the outbreak of the South Sudanese Civil War in 2013. Leading pro-government counter-insurgency forces in Wau State since 2014, Par was eventually ambushed and killed by SPLM-IO rebels loyal to Machar in 2017.
