Olesko is Slavic, Ukrainian in Origin.

Olesko is a rare East Slavic given name formed from Oles (Ukrainian/Belarusian pet form of Oleksandr/Aleksander) plus the affectionate suffix -ko. Through its root in Greek Alexandros, it carries the meaning “defender/protector of men” (from alexein “to defend” + anēr “man”). The spelling reflects Ukrainian phonology (Олесько); a Polish-influenced form Oleśko also occurs.

As a hypocoristic, -ko names are well-attested in medieval and early modern Ruthenian records and in folk usage across Western Ukraine and Belarus; in the 20th century Olesko began appearing independently on birth records, though it remains uncommon. The name should not be confused with the toponym Olesko in Lviv oblast. Related forms and short variants include Oles, Ales (Belarusian), Oleś (Polish), Les, Lesyk, and Olesik; formal equivalents are Oleksandr, Aleksander, and Alexander. Feminine cognates such as Olesia/Lesya are etymologically related in Slavic naming tradition.
