Leonard Borejko Chodźko (1800–1871) was a Polish historian, geographer, cartographer, publisher, archivist, and activist of Poland's post-November-1830-Uprising Great Emigration.

He was born on November 6, 1800, in Oborek, as the son of the nobleman Ludwik Chodźko [pl] and Waleria née Dederko.

[1] Chodźko was educated at the University of Vilnius, where he was a member of the Philomaths, a secret organization established in 1816 by Vilnius University students including Adam Mickiewicz, Tomasz Zan and Józef Jeżowski.

During France's July 1830 Revolution, he served as aide-de-camp to General La Fayette.

Around 1810, he married Olimpia Maleszewska, the daughter of the Polish economist Piotr Maleszewski [pl], who in turn was the natural son of Michał Jerzy Poniatowski, the Primate of Poland and the brother of King Stanisław August Poniatowski.
