The name Ondrej is derived from the Greek name Andreas, which means "manly" or "brave". It has its origins in the ancient Greek language and culture, dating back to the 5th century BCE.
The name Andreas was widely used in the Byzantine Empire and was later adopted by Slavic cultures, where it evolved into various forms, including Ondrej.
