Keaghan is Irish in Origin.

Keaghan is a modern Anglicized respelling of Irish Keegan, itself from the Gaelic surname Mac Aodhagáin (“son/descendant of Aodhagán”). Aodhagán is a diminutive of Aodh, an ancient Irish name meaning “fire,” so the sense is often rendered “little fire” or “descendant of little fire.”

As a family name, Mac Aodhagáin belonged to a prominent medieval brehon-law lineage of jurists and poets in Tipperary and Galway; the surname migrated to Egan/Keegan and then entered given-name use across the English-speaking world in the late 20th century. Keaghan remains the rarer spelling, chosen for its Gaelic flavor and the soft “KEE-gən” sound. Variants include Keegan, Keagan, Kegan, Keeghan, Keighan, and Egan; related Gaelic forms are Aogán and Aodhán (source of Aidan). Usage is largely masculine but occasionally unisex.
