Nikolai Nikolayevich Onoprienko (Russian: Николай Николаевич Оноприенко, Ukrainian: Микола Миколайович Онопрієнко; 19 December 1911 – 12 November 1979) was a Red Army colonel and World War II Hero of the Soviet Union.

[2] Onoprienko was born on 19 December 1911 in the village of Uil in Aktobe Region to a peasant family of Ukrainian ethnicity.

[4] Shortly afterwards, Onoprienko was admitted to the Combined Central Asian Red Banner Military School, from which he graduated in 1934.

After leaving the hospital in February 1942, Onoprienko became commander of the 134th Rifle Brigade's mortar battalion on the Bryansk Front.

[2][3] At the beginning of the East Prussian Offensive in January 1945, the regiment broke through German lines and reportedly advanced more than 10 kilometers in five days.

During the assault on Danzig, division commander Major General Sobir Rakhimov was killed on 26 March.

Onoprienko took command and completed the division's assault on Danzig before being replaced by Major General Kuzma Grebennik on 30 March.

On 19 April, the advanced forces of the division crossed the eastern branch of the Oder and were stopped by German troops positioned on a large river island.

On the night of 20 April, the advance regiment of the division crossed the western branch of the Oder and created a bridgehead.

Onoprienko attacked the main objectives and captured high ground and a brick factory.

From these positions, the regiment reportedly repulsed 18 counterattacks and provided a bridgehead for the crossing of the rest of the division.

On 29 June, Onoprienko was awarded the title Hero of the Soviet Union[11] and the Order of Lenin.
