Stephen M. O'Mara

Stephen Mary O'Mara (28 December 1883 – 11 November 1959) was an Irish businessman and republican politician in Limerick.

O'Mara was the third son of Stephen O'Mara, Snr, a former Mayor of Limerick and briefly an Irish Parliamentary Party MP. His elder brother James was an early supporter of Sinn Féin, which Stephen also joined after the Easter Rising. He was re-elected mayor in January 1922, and opposed the Anglo-Irish Treaty.

In March 1922, there was a stand-off in Limerick city between pro-Treaty and anti-Treaty units of the Irish Republican Army during the transfer of bases by the withdrawing British Army. O'Mara negotiated a resolution to this. In June a general Civil War broke out across the nascent Irish Free State. The City Police Force was replaced in July by the Free State Civic Guard. The evening before the 1922 general election, de Valera, O'Mara, and Boland dined together and discussed a possible grand coalition government. O'Mara joined Fianna Fáil on its formation in 1926. O'Mara died less than two months later in the Mater Hospital, Dublin.
