Flannon is Irish in Origin.

Flannon is a rare variant spelling of Flannan, the Anglicized form of Irish Gaelic Flannán, from Old Irish flann ‘red, ruddy, crimson’ plus the diminutive suffix -án, yielding ‘little red one’ or ‘ruddy-hued.’ It shares the flann root with surnames such as Ó Floinn (Flynn) and Ó Flannagáin (Flanagan) but remains a distinct given name. The name appears in Latin as Flannanus.

Attested in early medieval Ireland, it is most closely linked to Saint Flannan of Killaloe, a 7th‑century bishop and missionary whose veneration endowed the name with ecclesiastical prestige and inspired place-names including the Flannan Isles in the Outer Hebrides and St Flannan’s Cathedral in Killaloe, County Clare. While uncommon today, it surfaces sporadically in Ireland and the diaspora. Variants include Flannán (Irish), Flannan/Flannon (English spellings), and the short form Flann; feminine Flanna occurs rarely, and related surnames Flynn and Flanagan share the same etymological root.
