The leader of Sinn Féin (alternatively known as the Uachtarán Shinn Féin or President of Sinn Féin) is the most senior politician within the Sinn Féin political party in Ireland. Since 13 November 1983, the office has been held by Gerry Adams, following the resignation of Ruairí Ó Brádaigh as leader of the party.

The deputy leader of Sinn Féin is Mary Lou McDonald.

The leader of Sinn Féin in Northern Ireland is Michelle O'Neill.

The post of the President of Sinn Féin was officially created in 1905 when Arthur Griffith founded the party. Edward Martyn, a cultural activist and playwright was selected as the first president at its first annual Ard Fheis on the 28 November 1905. Unlike other Irish political parties, most notably Fine Gael and Fianna Fáil, the President of Sinn Féin does not have the power to dismiss or appoint their deputy and to dismiss or appoint parliamentary party members to front bench positions. These decisions are taken by the Ard Chomhairle (National Executive).

In the Northern Ireland Assembly, Sinn Féin is in government under a power-sharing agreement with the Alliance Party, Democratic Unionist Party, Social Democratic and Labour Party and the Ulster Unionist Party. The President of Sinn Féin does not act as the Deputy First Minister of Northern Ireland, If the President is not a member of the Assembly, then an MLA of the party is appointed as Leader in the North to replace him or her.
