Antóin Commane (in full, Antoin Niall Commane; in Irish, Antóin Niall Ó Comáin) is tánaiste of Clan Ó Comáin, the Gaelic clan recognised by Clans of Ireland in 2025 under the patronage of the President of Ireland. He was appointed to the clan's Privy Council in 2025. He is also Younger of Kinfauns.
The Chief's son, Antóin serves as heir designate under the Brehon tradition of tanistry, not primogeniture. The office does not guarantee succession. When the Chief dies, it is the clan members who will select the next Chief, choosing the most able, not merely the nearest in blood.
Antóin advises the Chief and deputises in his absence. He represents the clan at official functions, and in March 2026 he stood for Clan Ó Comáin at the Clans of Ireland annual gathering in Dublin, the first time an Ó Comáin officer had done so in the revived clan's own name.
