The Romanian Front (Russian: Румынский фронт) was a major formation of the Imperial Russian Army during the First World War.
The Front was created in mid-December 1916 out of the headquarters of the former Russian Danubian Army. Nominally the commanding officer of the front was Ferdinand I of Romania, however the de facto power lay in his "deputies": Russian generals delegated by the Stavka.
Initially the front consisted of three weakened armies: the 4th Army, 6th Army and 9th Army. Soon it was joined by the forces of 1st Romanian Army (under General Constantin Cristescu) and Second Romanian Army (under Alexandru Averescu), and in September 1917 by the Russian 8th Army.
Following the Russian Revolution the front disintegrated and most of its soldiers withdrew towards Moldavian Democratic Republic and Ukrainian People's Republic.
