Marko Vovchok was a pseudonym of a famous Russian and Ukrainian writer. Vovchok contributed to Russian literature by publishing works in the Russian language and to Ukrainian literature by publishing works in Ukrainian langauge.

While there is a broad consensus about the authorship of the Russian language works published under pseudonym Marko Vovchok (it was Mariya Lobach-Chuzhenko, also known as Mariya Markovytch during her first marriage and by her maiden name Mariya Vilinskaya, 1833 – 1907), to this day there is no consensus among literary historians as to the authorship of the Ukrainian language works published under this pseudonym: today most modern scholars believe that Vilinskaya's first husband, a Ukrainian folklorist and writer Opanas Markovytch (1822 - 1867), was likely either the sole author of Ukrainian language works of Marko Vovchok or at the very least the co-author of those works).
