Meaning & origin
Theseus is a rare choice in the United States, first recorded in 2010 and ranking 5,045th in 2025, with a frequency of about 1 in 89,899 newborns. Its peak came in 2015, after which its trajectory has been falling. The name has not yet appeared among the top baby names in any state. While still uncommon, Theseus carries the weight of Greek mythology, making it a distinctive option for parents drawn to classical names. Its mythological associations with heroism and adventure may appeal to those seeking a name with a story, though its rarity means it remains a bold and unconventional pick.
Theseus is a name of ancient Greek origin, borne in Greek mythology by the legendary king of Athens who slew the Minotaur. The etymology is debated; it may derive from the Greek verb 'tithemi' (to place, to set) or be connected to 'thesmos' (institution, custom). The name has been used in classical contexts since antiquity but only entered modern usage as a given name in the 20th century.
