Keane is an Irish surname that finds its roots in the Gaelic language of the Irish people. It originates from the surname Ó Catháin, meaning "descendant of Cathán," and is therefore associated with a lineage that would have been noted for its martial prowess.

The personal name Cathán is a diminutive of the Gaelic word cath, meaning "battle." Consequently, the name Keane conveys the sense of "descendant of the warrior" or "family of a fighter." Such an etymology indicates that early bearers of the name likely enjoyed a reputation for courage or for service in warfare.

Throughout history the surname has appeared in a number of spellings, reflecting both regional pronunciation and the process of Anglicisation. Common variants include Kane, Keane, Kean, Keen, Keene and Keegan. Some writers have suggested that the name may also derive from Middle English forms such as kene (meaning "known") or from pre‑7th‑century personal names with the element cene or cyne (meaning "royal"). While these alternatives exist, the primary derivation remains the Gaelic lineage described above.

The earliest documentary record of an Anglicised form appears in the Curia Regis Rolls of Suffolk in 1207, where a person named Adam Kene is mentioned during the reign of King John (1199‑1216). This evidence establishes that the name, or a close variant, was in use in England well before the Tudor period.

London church records from the late sixteenth and early seventeenth centuries provide further early attestations. In 1576, an Agnes Keene married Thomas Gryffyn at St. Gregory by St. Paul. Later, in 1590, Hester Keane, daughter of John Keane, was christened at St. Bartholomew's, Exchange. These entries demonstrate the presence of the name in the capital during a period of significant urban migration.

In the nineteenth century, the great Irish Famine prompted the emigration of many families bearing the surname. One such account records a Joanna Keane, aged 20, who left Cork aboard the ship Adirondack bound for New York on 11 April 1846. Her departure is one of many documented examples of Keane emigrants seeking refuge abroad.

Within Ireland itself, the name remains most densely concentrated in County Derry in Ulster and in County Galway in Munster. Historically, several septs carried the name—O’Cathain in the north and Keane in the west—each establishing its own local authority and social networks. The survival of these septs into the modern era has allowed the name to retain a strong geographic identifier within Irish society.

Due to centuries of emigration, the surname has spread to other English‑speaking countries. In the United States, Australia, the United Kingdom and Canada, individuals bearing the name Keane have established households and, in some cases, contributed to public life. Nonetheless, the greatest density of the surname continues to be found in Ireland, where contemporary bearers maintain the cultural heritage that traces back to their Gaelic forebears.
