Ukrainian People's Republic or Ukrainian National Republic (Українська Народна Республіка, Ukrayins'ka Narodna Respublika, abbreviated УНР, UNR) was a republic in a part of the territory of the modern Ukraine after the Russian Revolution, eventually headed by Symon Petlura.

By the results of the Polish-Bolshevik War, after the Peace of Riga in March 1921, Halychyna, the western part of the traditional territory of Ukraine, had been incorporated into Poland, and the larger, central and eastern part became part of the Soviet Union as the Ukrainian SSR.
