Casey

Casey is an Irish surname from the Gaelic Cathasach, meaning "vigilant" or "watchful in battle," derived from cath, meaning "battle." It became a popular given name in North America during the 20th century, used for both boys and girls. Casey has a friendly, alert quality — the name of someone who pays attention, who notices things, who is always ready.

Casey ranks #164 among America's most popular pet names, a true gender-neutral option that works equally well for any companion. It has an easy, breezy friendliness that feels thoroughly American — the kind of name that shows up in baseball fields and small-town streets with equal comfort. Casey Jones, the legendary railroad engineer, gave the name an association with dedication and courage that has persisted in popular culture for over a century. It suits companions who are alert, engaged, and always seem to know what is happening.
