Meaning & origin
Theia is a rare but rising name in the United States, first recorded in 1967 and climbing in popularity since 2005. In 2025, it holds rank 1981, with about 1 in 16,570 newborn girls receiving the name. Its peak year to date is 2024, reflecting a steady upward trajectory. Geographically, Theia is most common in Minnesota, Maryland, and Florida, suggesting a broad but niche appeal. The name's mythological roots give it a celestial and ancient feel, appealing to parents drawn to goddess names and short, distinctive sounds. Theia's rise aligns with broader trends favoring mythological and nature-inspired names, yet it remains uncommon enough to stand out.
Theia comes from the Greek Θεία (Theia), derived from θεός (theos) meaning 'god' or 'goddess.' In Greek mythology, Theia was a Titaness, daughter of Uranus and Gaia, and mother of Helios (sun), Selene (moon), and Eos (dawn). The name has been used in astronomy for one of Earth's hypothesized protoplanets, but as a personal name it remained rare until the late 20th century, gaining modern attention for its mythological resonance and short, vowel-rich sound.
