Gerard Adams is an Irish republican politician who was the president of Sinn Féin between 13 November 1983 and 10 February 2018, and served as a Teachta Dála (TD) for Louth from 2011 to 2020. From 1983 to 1992 and from 1997 to 2011, he followed the policy of abstentionism as a Member of Parliament (MP) of the British Parliament for the Belfast West constituency.

The president of Sinn Féin is the most senior politician within the Sinn Féin political party in Ireland. Since 10 February 2018, the office has been held by Mary Lou McDonald, following the decision of Gerry Adams to stand down as leader of the party and not seek re-election again. Unlike other political parties, 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.
