Ostap Meaning Origin and Vibe

Ostap is a traditionally masculine name originating as a Slavic form of the Greek name Eustathios, meaning "steadfast" or "stable." Historically prominent in Ukrainian and Polish cultures, the name carries a strong, traditional, and resilient mood. Its usage in the United States remains culturally specific, often serving as an identifier within Eastern European immigrant communities rather than achieving general popularity. The name’s historical depth reinforces a personality vibe that is grounded and reliable. While globally defined as male, its scarcity in the US makes it a distinct cultural marker.
