Russian separatist forces in Ukraine, primarily the People's Militias of the Donetsk People's Republic (DPR) and the Luhansk People's Republic (LPR), were pro-Russian paramilitaries in the Donbas region of eastern Ukraine. They were under the overall control of the Russian Federation, and were also referred to as Russian proxy forces. They were active during the war in Donbas (2014–2022), the first stage of the Russo-Ukrainian War. They then supported the Russian Armed Forces against the Ukrainian Armed Forces during the 2022 Russian invasion. In September 2022, Russia annexed the DPR and LPR, and began integrating the paramilitaries into its armed forces. They are designated as terrorist groups by the government of Ukraine.

Ukrainian volunteer battalions were militias and paramilitary groups mobilized as a response to the perceived state of weakness and unwillingness of the regular Armed Forces to counter rising separatism in spring 2014. They trace their origins to the "Maidan Self-Defense" militias formed during the Euromaidan in 2013. The earliest of these volunteer units were later formalized into military, special police and paramilitary formations in a response to the Russian military intervention in Ukraine in 2014. Most of the formations were formed or placed under command of the Ministry of Internal Affairs — as "Special Tasks Patrol Police" — and Ministry of Defence — as "Territorial defence battalions". A minority of battalions were independent of state control.
The combatants of the war in Donbas included foreign and domestic forces.
