Kaulder

While Kaulder might sound like a sturdy surname-style choice, it is in fact a pop culture creation, used for the protagonist of the 2015 movie, The Last Witch Hunter. Portrayed by Vin Diesel, the character is an immortal witch hunter, helping to keep the peace between humans and the magic users

Strong and distinctive, Kaulder is reminiscent of surnames and place names such such as Calder ("rocky water"), Keldan ("spring, well"), Colter ("keeper of horses"), Cauldwell ("cold spring"), and Caledonia ("hard, rocky land"), though it may also be a play on the word cauldron.

The name entered the US charts following the release of the film, with 32 boys given the name in 2016. More recent counts have seen it given to around 10 boys a year.

Pronounced KAUL-der.

As of October 2026, Kaulder ranked #7432 for boys in US births in 2025 SSA, peaked at #3480 for boys in 2016.
