Woulfe (1923) gives Shanahan as an anglicised form of Ó Seanacháin, 'descendant of Seanachán' (diminutive of seanach, old, wise), the name of a Dalcassian family who were chiefs of Ui Ronghaile in the east of Thomond until 1318.

The Shanahan coat of arms

The design shown is a coat of arms associated with the Shanahan surname. In Irish and British heraldry a coat of arms is granted to one person and passes to their heirs; it does not belong to everyone who shares the surname. Many families still use the arms of their name as a symbol of their heritage.
