Athanasia is Greek in Origin.

Rooted in Ancient Greek, Athanasia derives from ἀθανασία (athanasía), meaning “immortality,” built from the privative a- “not” and thanatos “death.” As the feminine counterpart to Athanasios (Latinized Athanasius), it carried strong theological overtones of eternal life for early Christians.

Usage is documented in Byzantine records and Orthodox calendars, notably borne by Saint Athanasia of Aegina (9th century), which helped preserve the name across Greece and Cyprus. It remains most common in Hellenic and wider Eastern Orthodox communities, with sporadic appearance elsewhere. Variants and cognates include Athanasía (Greek orthography), Thanasia (transliteration variant), Atanasia (Spanish, Romanian), Atanásia (Portuguese), and Afanasiya/Afanasya (Russian). Diminutives and modern forms include Nasia, Sia, and the Anglicized Nancy often used by the Greek diaspora. The name’s enduring appeal rests on its luminous meaning - “undying” or “everlasting” - and its connection to faith and resilience.
