Kiely

Meaning & origin

Kiely is a given name that emerged in the United States in the late 20th century, first appearing on Social Security Administration records in 1969. While its exact origin is debated, it is most commonly understood as an Anglicized form of the Irish surname Ó Cadhla, meaning 'descendant of Cadhla', with Cadhla translating to 'beautiful' or 'graceful.' The name has never reached widespread popularity; its peak year came in 2008, after which it declined in use until a recent resurgence. Since 2022, Kiely has been on a rising trajectory, though it remains rare, with a 2025 rank of 14,942 and an incidence of about 1 in every 321,453 births. Given its Irish roots and modern sound, Kiely fits alongside other surname-style names like Riley and Quinn. Its top U.S. states of use are not concentrated in any particular region, reflecting a broad but sparse distribution.

Kiely is likely an Anglicized form of the Irish surname Ó Cadhla, which means 'descendant of Cadhla', a personal name derived from the Irish word 'cadhla' meaning 'beautiful' or 'graceful'. The surname has been in use in Ireland for centuries, but its adoption as a given name is a more modern phenomenon, particularly in the United States, where it first appeared on the Social Security Administration's baby name records in 1969. The spelling Kiely may have been influenced by other popular -ee ending names like Riley and Kiley, as well as the similar-sounding surname Keely.
