Meaning & origin
Fallon is a stylish Irish surname-turned-given name that saw its peak popularity in 1982, ranking 778th most common for girls in 2025. After a dip, it has been steadily rising since 2003, reflecting a resurgence of interest in names from the 1980s. The name is particularly prevalent in West Virginia, Iowa, and Arkansas, and is often paired with similar stylish unisex names like Blair. Its use as a given name was propelled by pop culture, but its Irish roots give it a solid historical foundation.
Fallon is a transferred use of the Irish surname Ó Fallamhain, meaning 'descendant of Fallamhain'. The personal name Fallamhain is thought to derive from 'follamhnas', meaning 'supremacy' or 'leadership'. The surname was anglicized as Fallon, and its use as a given name emerged in the 20th century, popularized in America partly by the actress Fallon Taylor and the character Fallon Carrington Colby on the 1980s television series 'Dynasty'.
