Novorossiya or New Russia, also referred to as the Union of People's Republics, was a project for a confederation between the self-proclaimed Donetsk People's Republic (DPR) and the Luhansk People's Republic (LPR) in Eastern Ukraine, both of which were under the control of pro-Russian separatists.

The Donetsk People's Republic is an internationally unrecognized republic of Russia, comprising the occupied parts of eastern Ukraine's Donetsk Oblast, with its capital in Donetsk. The DPR was created by Russian-backed paramilitaries in 2014, and it initially operated as a breakaway state until it was annexed by Russia in 2022.
