Delaney is Irish in Origin.

Delaney is an Irish surname-turned-given name with two principal etymologies. One derives from the Gaelic Ó Dubhshláine, "descendant of Dubhshláine," a personal name combining dubh "dark, black" with Sláine, likely connected to the River Slaney; it is commonly interpreted as "descendant of the dark one of Slaney." A second route comes via Norman French de l'aunaie, meaning "from the alder grove," brought to Ireland by settlers and later absorbed into local usage.

As a given name, Delaney gained traction in the English-speaking world in the late 20th century, used for both sexes but most popular for girls in North America. The surname appears in Irish records from medieval times, especially in Leinster. Modern variants and spellings include Delany, Delanie, Delainey, Delayne, and DeLaney, with short forms Laney/Lainey or Del. The name balances sprightly, modern energy with deep Celtic and Norman roots.
