Caspian draws its salt-tinged charm from the Caspian Sea—Mare Caspium in classical Latin—whose name likely echoes the ancient Caspii people who once traded along its southern shores. Introduced to many parents through C. S. Lewis’s valiant Prince Caspian, the name carries connotations of maritime adventure, royalty and distant geography without feeling archaic. In the United States, its voyage from fringe curiosity to emerging favorite has been steady: fewer than 20 newborns bore the name at the turn of the millennium, yet 492 did so in 2024, lifting Caspian into the national top 500 for the first time. The three-syllable pronunciation KAS-pee-uhn glides easily in English and shares structural kinship with classical names like Julian or Adrian, giving it both a contemporary and time-tested resonance. As Latin America’s expansión cultural celebrates fluid, nature-infused names, Caspian offers families a nautical nod and a touch of literary nobility while remaining refreshingly uncommon.
