Meaning & origin

Athanasius is a rare but enduring name with deep roots in Christian history. First recorded in U.S. data in 2001, it has seen a slow but steady rise in use since 2004, ranking 5045 in 2025. Its peak year was 2023. The name carries the strong meaning 'immortal', appealing to parents seeking a name with religious significance and classical gravitas. Despite its rarity, its form is recognizable from the famous Saint Athanasius, making it a distinctive choice with historical weight.

Athanasius derives from the Greek word 'athanatos' (ἀθάνατος), meaning 'immortal' or 'deathless', composed of 'a-' (not) and 'thanatos' (death). It was notably borne by Saint Athanasius of Alexandria (4th century), a key figure in early Christian theology who defended the doctrine of the Trinity. The name has been used throughout Christian history, especially in Eastern Orthodox traditions, and remains in occasional use in modern times.
