Casey
/ˈkeɪ.si/
Casey comes from the Irish surname Ó Cathasaigh, derived from the given name Cathassach, which may mean “vigilant” or “watchful.” The Anglicized surname Casey is one of the most common Irish family names found in America today.
The name’s most famous association is with Casey Jones (1863-1900), the railroad engineer who died saving his passengers in a train wreck near Vaughan, Mississippi.
His nickname came from Cayce, Kentucky, where he grew up. A popular ballad about his heroism spread the name nationwide in the early 1900s.
What the name Casey means
Casey also resonates in baseball lore through Casey at the Bat (1888), Ernest Thayer’s narrative poem about a slugger who strikes out in the clutch.
The poem became one of the best-known works of American light verse and cemented Casey as a quintessentially American name.
The name peaked for boys at No. 80 in 1987, when it was widely used for both genders. Casey was among the earliest modern unisex names in America, equally popular for girls throughout the 1980s and 1990s.
By 2024, Casey had climbed to No. 310 with 1,096 births for boys, a notable increase from its low point around 2016-2018 when it hovered near No. 555. The recovery of roughly 250 positions is significant.
Casey’s dual literary and historical associations - the heroic engineer and the fictional ballplayer - give it a distinctly American character that few Irish-origin names share.
The name’s unisex quality, while once novel, has become more common in the naming landscape. Casey retains an easygoing, approachable warmth that has kept it in use across multiple generations.
