Connolly is a surname that originates from the island of Ireland, where it evolved from Gaelic and Celtic linguistic roots and is traditionally associated with Christian heritage.

The modern rendering of the name Connolly derives from the Gaelic patronymic Ó Conghaile, meaning descendant of Conghal. The personal name Conghal is itself taken from the Gaelic noun congal, which denotes high or noble, thereby characterising bearers of the surname as individuals of distinguished lineage. A further decomposition of the name shows the elements con (hound) and gal (valor), so that Conghaile may be interpreted literally as hound of valor, and the entire patronymic as descendant of the Hound of Valor.

Historically the surname belonged to the ancient Connacht sept known as the O'Conghaile. Over time the sept split into three principal branches. The chief line settled in County Meath and was one of the revered Four Tribes of Tara, connected with the seat of the Irish High Kings on the Hill of Tara. The second line operated within the ancient Kingdom of Oriel, covering what is now County Monaghan, where the O'Connollys ruled alongside the McMahons and McKennas until the end of the twelfth century. The Munster branch established itself in West Cork, where the surname was frequently written as O'Coingheallaigh, an appellation meaning faithful, reliable and diligent.

One of the most prominent contemporary figures bearing the surname is James Connolly (1868–1916), a celebrated labour leader and signatory of the Irish Declaration of Independence, whose example has ensured that the name continues to carry a legacy of public service and activism.

The earliest documented appearance of the family name is found in the Fiants Records of County Monaghan, dated 1591, under the entry Tirlogh O'Connola, Chief and Vice‑Marshal to MacMahon, which places the surname firmly within the political records of the reign of Queen Elizabeth I of England, affectionately known among contemporaries as “Good Queen Bess”.

Through these documented instances it is clear that the surname Connolly has endured for many centuries, its bearers having played significant roles in the historical, political and social fabric of Ireland.
