Onix as a Baby Name. Meaning and Origin of Onix

What is the meaning of the name Onix ?

The baby name Onix is a Unisex name , 2 syllables long and is pronounced OH-niks (IPA: /ˈoʊ.nɪks/).

Onix is Greek in Origin.

Onix derives from Greek onyx, meaning “claw” or “fingernail,” the term that came to denote the banded gemstone; through Latin onyx it entered European languages. As a given name, Onix mirrors the gemstone spelling Onyx but often adopts a Spanish-influenced spelling without the y, yielding a sleek, modern look. It is used for all genders, with a strong, mineral-inspired feel and ties to the deep black stone’s protective lore.

Usage of Onix as a first name remained rare until the late 20th century, appearing in Spanish-speaking communities - most visibly in the Caribbean and Latin America (e.g., Puerto Rican shortstop Onix Concepción) - and later rising in English-speaking countries alongside other nature and word-names, helped by pop-cultural visibility (such as the Pokémon character Onix). Variants and related forms include Onyx (English), Ónix (Spanish), and Onice (Italian); shortened forms like Nyx or Oni also occur. The name evokes steadiness, resilience, and elegant simplicity.
