Sebastien is the French form of Sebastian, which comes from the Greek sebastos and means "venerable" or "revered"; the Latin Sebastianus originally meant a man from Sebaste, a city in Asia Minor. Saint Sebastian, the Roman soldier shot with arrows, made the name popular throughout Europe, and the French spelling is common in Quebec and Louisiana.
