Korsak

Korsak is a surname of Slavic origin found in several Eastern European countries and among diaspora communities. The name may also appear as a given name or as part of a patronymic in some contexts. The exact etymology is uncertain and likely varies by region; in some cases it is believed to derive from a nickname or diminutive form of a given name, while in others it may reflect an ancestral occupation or place of origin.

In transliteration from Cyrillic and other scripts, the name appears in several variants, including Korsak, Korsakov, Korsakow, and Korsakoff, depending on language and historical period. The form without the -off suffix is more common in Polish and Ukrainian records, while -ov/-off is typical in Russian transliteration.

Geographically, Korsak is most frequently encountered in Poland and Ukraine, with communities also in Russia, Belarus, Lithuania, and among emigrants in North America and other regions.

Notable bearers of the surname include individuals in fields such as academia, arts, and public life, reflecting its broad distribution across Central and Eastern Europe. Because it is a relatively common Slavic surname, it has no single defining biography.
