Meaning & origin
Kiley first entered the U.S. popularity charts in 1958, but its strongest period was the 2000s, when it peaked at rank 325 in 2008. Since 2009, the name has been steadily falling in use, and by 2025 it ranked 2,778, with only 1 in 26,349 newborns receiving the name. The name was most popular in Florida during its peak. Although its exact origins are debated, Kiley fits a modern pattern of feminine names ending in the 'lee' sound, a style that includes similar names like Kylee, Haylee, and Bailey. Its sharp decline since the late 2000s suggests it is currently out of fashion, but it remains a recognizable and straightforward choice.
Kiley likely emerged as a modern feminine given name, either as a variant of Kyle or from the Irish surname Ó Cadhla. The surname means 'descendant of Cadhla', with Cadhla meaning 'graceful' or 'beautiful'. The name gained popularity in the United States in the late 20th century, particularly in the 1990s and 2000s.
