McCaughey is an Irish surname. Spelling variations include: McHaughey, MacCaughey, McGaughey and O'Coffey, among others. The anglicisation comes from the original “Mac Eochaidh”.

The McCaugheys are descendants of the ancient Dál Fiatach dynasty, rulers of the Ulaid, modern day Ulster. The surname McCaughey is an anglicised form of the Irish surname “Mac Eochaidh”, meaning “son of Eochaidh” (son of the horseman) or “descendant of Eochaidh” (descendant of the horseman). The personal name “Eochaidh” was common in early medieval Ireland and appears among the ruling families of Ulaid, particularly the Dál Fiatach, the dynasty associated with eastern Ulster - particularly County Down. They trace their descent from Fiatach Finn mac Dáire, a King of Ulster and High King of Ireland in the 1st century AD.
