Pyotr Ivanovich Bartenev (Пётр Ива́нович Барте́нев; 13 October 1829 – 4 November 1912) was a Russian historian and collector of unpublished memoirs.

In 1856, he undertook the first publication of the correspondence of Tsar Alexis, which brought him to the attention of the leading Slavophiles.

[2] In 1863, Bartenev founded The Russian Archive, the first history journal in Russia.

Like its rival, Old Times in Russia, Bartenev's journal brought to light scores of unknown documents and memoirs from the 18th and early 19th centuries.

Prince Vorontsov's entire family archive was published in 40 volumes as a supplement to this periodical.
