Hydra is Greek in Origin.

Hydra is a rare given name of Greek and Latin origin. It comes from Greek hydra, “water-serpent,” rooted in hydōr, “water.” In classical mythology it names the many‑headed Lernaean serpent defeated by Heracles, a tale that lends associations of power, danger, and regeneration. Hydra also denotes the longest constellation in the sky and the Saronic Gulf island Ídra (often rendered Hydra in English), broadening the name’s celestial and geographic resonance. As a meaning, “water serpent” or simply “water” is primary.

As a personal name, Hydra sees sporadic modern use in English-speaking countries, often chosen for a bold, mythic, or astro‑nature vibe; it leans feminine but functions unisex. Variants and transliterations include Idra (common in Italian contexts) and Ídra; cognate spellings in Romance languages appear as Hidra. Related cultural echoes include the freshwater polyp genus Hydra and various pop‑culture references, which may color perception without defining the name’s classical roots.
