Meaning & origin

Thorin is a rare but increasingly popular boys' name of literary origin, directly inspired by the dwarf king Thorin Oakenshield from J.R.R. Tolkien's 'The Hobbit'. The name first appeared in U.S. records in 1968, but its real growth began in 1987, and it has been steadily rising since. In 2025, it was given at a rate of about 1 in every 12,747 newborns, ranking 1,376 nationally. Its peak year so far was 2023, reflecting a sustained interest in Tolkien-inspired names. Geographically, Thorin shows a strong western preference, with Idaho, Utah, and Washington among its top states, suggesting a particular resonance in areas with outdoor and fantasy culture. While the etymology is debated, the name's modern appeal rests entirely on its literary roots, and it remains a distinctive choice for fans of the fantasy genre.

Thorin is a name that first appears in J.R.R. Tolkien's fantasy works, most notably 'The Hobbit' (1937), where it is borne by a dwarf king. Tolkien likely drew on Old Norse elements, possibly combining 'Thor' (the thunder god) with a diminutive suffix. The name has no historical usage before Tolkien and has been adopted by parents inspired by the character.
