Brian O'Higgins, also known as Brian na Banban, was an Irish writer, poet, soldier and politician who was a founding member of Sinn Féin and served as President of the organisation from 1931 to 1933. He was a leading figure within 20th century Irish republicanism and was widely regarded for his literary abilities.

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.
