Meaning
used by C. S. Lewis for the Narnia prince (1950); probably from the Caspian Sea, named for the city of Qazvin and the ancient Cas tribe
The story
Caspian was used by C. S. Lewis for a character first appearing in 1950 in his Chronicles of Narnia: Prince Caspian, the rightful king of Narnia driven into exile by his evil uncle Miraz. Behind the Name traces the name itself with a hedge at every step: Lewis probably based it on the Caspian Sea, which was named for the city of Qazvin, which was itself named for the ancient Cas tribe. The published American record waited four decades after the book: about 19 boys in the 1990s, about 190 in the 2000s, about 1,400 in the 2010s, and about 2,570 so far this decade, already past the whole 2010s total. A sea, a city, an ancient tribe, and an exiled king: the chain is long, and the record is finally reading it.

share of the boys on the register for that year, SSB’s own figure
People who have or have had a Norwegian ID number, emigrants left out, from Statistics Norway’s name statistics (release of January 2026): by year of birth for 1945–2020 (everyone born that year who was ever registered in Norway, including people who registered later and people who have since died) and by year of naming from 2021; only first names carried by 200 or more living people are listed, counts under 4 are withheld, and SSB merges spellings that differ only by letters outside the Norwegian alphabet. The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.

First given names from provincial and territorial vital statistics across Canada; any name-sex-year under 5 is excluded at source, and small Quebec counts carry a randomized adjustment made at source. Shares divide by Statistics Canada’s count of live births for the year; the 2024 count is preliminary. Source: Statistics Canada, first names at birth (table 17-10-0147-01)
South Australia

In South Australia, 2 boys were registered as Caspian in 2017.
The count never rose above 2 in a year, too few to chart.
Births registered in South Australia (not all of Australia) by first name and year of registration, 1944–2017, from the state’s Births, Deaths and Marriages registry, which publishes every name down to a single birth in capitals; a spelling its export repeats inside a year is counted once, and from 2018 only a top 100 is published, so the series ends at 2017.

Austria
last on record 2024
Caspian is not on the 2025 record for Austria, which publishes every first name down to a single birth, so the name was not given there that year.
The count never rose above 3 in a year, too few to chart.
Live births in Austria by year of birth, 1984–2025, from Statistik Austria’s first-name statistics; spellings that differ only by special characters are counted together (umlauts stay apart), every name down to a single birth is published, and the count covers babies with Austrian citizenship only until 2009, every baby from 2010, and from 2015 also births abroad to mothers living in Austria. Shares divide by Statistik Austria’s count of live births from 2010, and before that by the file’s own total for the year.

Poland
last on record 2023
Caspian is not on the 2025 record for Poland, where names given fewer than 2 times in a year are withheld at source.
The count never rose above 7 in a year, too few to chart.
First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)
Scotland

Caspian is not on the 2024 record for Scotland, where spellings under 3 in total are suppressed at source.

Births registered in Scotland; different spellings count separately but accents are merged at source, and any spelling under 3 in total is suppressed. Source: National Records of Scotland, babies' first names
Not on the record in Spain, Mexico City, Argentina, Puerto Rico, Ireland and New Zealand: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown.
