Flinn
An Irish surname usually treated as a variant of Flynn, from a Gaelic name meaning “white” or “fair.”
The #6,357 most common surname in the United States (2010 Census) — about 1 in every 57,613 Americans shares it.
Etymology
Flinn is commonly explained as a spelling variant of Flynn, ultimately from Irish Gaelic Ó Floinn or related forms. The underlying personal name is usually linked to a word meaning “red” or “ruddy” in older Irish etymology, though some 19th-century writers connected it with a form meaning “white” or “fair.” The surname therefore most likely began as a Gaelic family name that was later anglicized in several spellings, including Flinn and Flynn.
History
The name is strongly associated with Ireland and appears in many anglicized forms, especially Flinn and Flynn. In older surname books it is often grouped with Flynn and treated as a variant spelling rather than a fully separate origin. In later records, Flinn survives as a less common form in both Ireland and the diaspora.

Fun fact
Older reference works sometimes tried to relate Flinn to Irish words for “white” or even to landscape imagery, showing how uncertain 19th-century surname etymology could be.
