Paddy J. McLogan (Irish: Pádraig Mac Lógáin) (1899 – 21/22 July 1964) was President of Sinn Féin from 1950–52 and again from 1954 to 1962.
In 1936, the IRA set up Cumann Poblachta na hÉireann, with McLogan as chairman and one of many Sinn Féin members of the party.
In 1950 he succeeded Margaret Buckley as President of Sinn Féin, until 1952, and resumed that role in 1954 and was to remain in the post until 1962, when he resigned from the party.
Around this time, he also owned a public house on the Main Street in Portlaoise, County Laois, which is now known as the one and only "Ryan's".
He died on 20 or 21 July 1964, at his home at 11 Herbert Road, Blanchardstown, County Dublin,[4] as a result of an accident involving a 9mm Walther pistol.
