Ukrainian Socialist-Revolutionary Party (Russian: Украинская партия социалистов-революционеров Ukrainian: Українська Партія Соціалістів-Революціонерів) was a political party in the Russian Republic from 1917. It was created in April 1917 based on separate groups and circles of SRs that existed on the territory of Ukraine since 1905. The left faction of the party dissolved it in 1918 forming a new party, while the Ukrainian Socialist-Revolutionary Party was recreated in January 1919 by its right faction members.
