Ciel is a modern given name taken from the French common noun meaning “sky” or “heaven,” ultimately from Latin caelum. Used as a rare unisex choice, it appeared sporadically in Francophone registers but gained broader visibility in the late 20th and early 21st centuries alongside English-language nature and word names. Pop culture, notably the manga/anime character Ciel Phantomhive, helped introduce the name to non-French audiences, and it is occasionally adopted in Japan via katakana. While never common, it has steady niche appeal in France, Canada, and the United States.

Variants and related forms include Cielle (an anglicized feminine elaboration), the Spanish Cielo and Ciela, and the affectionate Spanish diminutive Cielito; cognates also appear across Romance languages (e.g., Catalan Cel). The meaning evokes the open sky and the celestial realm, suggesting qualities such as serenity, aspiration, expansiveness, and transcendence.
