Nassos is Greek in Origin.

Nassos (Greek: Νάσος) is a modern Greek diminutive and standalone given name derived chiefly from Athanasios/Athanasius, from Greek a- “not” + thanatos “death,” yielding the meaning “immortal, deathless.” The root name rose to prominence in late antiquity through Saint Athanasius of Alexandria and remained common throughout the Byzantine and post‑Byzantine Greek world, anchoring Nassos within the Hellenic naming tradition.

In contemporary Greece and the diaspora, Nassos or Nasos functions both as an affectionate short form and as an independent name. Related variants and cognates include Athanasios (formal), Athanasius (Latinized), Thanasis and Thanos (nicknames), and the feminine Athanasia with diminutives Nasia and Sia. Spelling varies between Nassos and Nasos in transliteration. The name appears among 20th‑ and 21st‑century Greek artists and writers, such as painter Nassos Daphnis and poet Nasos Vagenas, giving it a cultured, modern profile while preserving venerable roots.
