Meaning & origin
Delaney first appeared on the U.S. name charts in 1939, but remained rare until the late 20th century. Its trajectory has been rising since 1985, reflecting a broader trend toward Irish surnames as feminine first names. In 2025, Delaney ranked 242nd, with a rate of about 1 in 1,253 girls. Its peak year was 2004, when it reached 102nd place. Popularity has been especially strong in Maine, South Dakota, and Delaware, where Delaney ranked higher than the national average. The name fits a modern, unisex style without being overly trendy.
Delaney is an anglicized form of the Irish surname Ó Dubhshláine, meaning 'descendant of Dubhshláine.' The first element dubh means 'dark' or 'black,' and slán means 'challenge' or 'defiance.' Originally a surname in County Laois, Ireland, it transitioned to a given name in the late 20th century, especially for girls, influenced by similar sounding names like Courtney and the popularity of surnames as first names.
