Antoni Oleszczyński (16 January 1794, Krasnystaw - 28 February 1879, Paris) was a Polish graphic artist and copperplate engraver.
Upon graduating, he was awarded a gold medal for his engraving of Alexander Kokorinov, after a portrait by Dmitry Levitzky.
He then went to Paris, again at government expense, where he worked in the studios of the painter Jean-Baptiste Regnault and the engraver Théodore Richomme.
In 1832, he received an offer of employment at the Academy, but he chose to become part of the Great Emigration and settled in Paris, where he remained until his death.
