Meaning & origin
Caspian entered the U.S. baby name charts in 1998, a rare and evocative choice drawn from the world's largest inland sea. In 2025, it ranked 491st, given to approximately 1 in 2,782 baby boys, and reached its peak popularity that same year, reflecting a steady upward trajectory that began in 1999. The name has been adopted primarily by families in Maine, Hawaii, and Oregon, states that often favor distinctive nature-inspired names. Its literary connection to C.S. Lewis's character Prince Caspian likely boosted awareness, though the name retains an appeal as a geographical and historical reference. Caspian remains an uncommon but recognizable choice, climbing slowly in usage without entering the mainstream.
Caspian is derived from the name of the Caspian Sea, which itself comes from the Latin 'Caspium mare,' from the Greek 'Kaspion pelagos,' ultimately named after the ancient Caspii people who lived near its shores. The name appears in the Bible (Caspian is not directly biblical, but the Caspian Sea is mentioned in apocryphal texts). In modern English, Caspian gained popularity as a given name, partly due to its use in C.S. Lewis's 'The Chronicles of Narnia' (Prince Caspian, 1949), though the character's name was inspired by the sea.
