Seaghan is Irish, Scottish Gaelic in Origin.

Seaghan is an Irish Gaelic variant of Seán, the Irish form of John. Via Anglo-Norman French Jean and Latin Iohannes from Hebrew Yohanan, it carries the meaning “God is gracious.” The spelling Seaghan reflects older Gaelic orthography in which gh indicates lenition and is typically silent; pronunciations most often align with “Shawn,” though regional speech may yield “Shan.” Rarer than Seán today, Seaghan appears in early modern Irish records and saw periodic revival alongside Irish-language resurgence.

Established in Ireland from the 13th century onward, the name was borne by chieftains, poets, and clerics, embedding it across Irish cultural history. Variants and cognates include Seán, Seaghán (with fada), Seánín (diminutive), and the Anglicized forms Shane, Shaun, and Shawn; related Celtic cognates are Scottish Gaelic Iain, Welsh Ioan/Ieuan, and Breton Yann. Feminine counterparts include Siobhán (Joan) and Sinéad (Jane).
