Olier is French in Origin.

Olier is the Breton form of Olivier, ultimately deriving from Latin oliva “olive (tree).” The name’s medieval prestige rose through the chanson hero Oliver (companion of Roland), and in some sources it was blended with Germanic naming traditions, though the “olive tree” etymology is the most accepted. As a given name, Olier conveys associations of peace, resilience, and prosperity tied to the olive’s symbolism.

Usage is concentrated in Brittany, where Breton-language orthography preserves the form Olier alongside the related Breton/Ouest-French spelling Ollivier. The name appears in regional records from the later Middle Ages and experienced periodic revival with modern Breton cultural movements. Outside Brittany, Olier is more familiar as a French surname - borne by Jean-Jacques Olier (1608–1657), founder of the Sulpicians - yet it remains a distinctive Breton given name. Variants and cognates include Olivier (French), Oliver (English, German, Scandinavian), Oliviero (Italian), Óliver (Spanish), Olivério (Portuguese), Oilibhéar (Irish), Olivér (Hungarian), and Oliwier (Polish). Nicknames: Oli, Ollie.
