Douglas Ross Hyde, known as An Craoibhín Aoibhinn, was an Irish academic, linguist, scholar of the Irish language, politician, and diplomat who served as the first president of Ireland from June 1938 to June 1945.

The president of Ireland is the head of state of Ireland and the supreme commander of the Irish Defence Forces. The presidency is a predominantly ceremonial institution, serving as the representative of the Irish state both at home and abroad. Nevertheless, the office of president is endowed with certain reserve powers which have constitutional importance. When invoking these powers, the president acts as the guardian of the Irish constitution. This representative and moderating role is in keeping with the president's solemn oath to "...maintain the Constitution of Ireland and uphold its laws..", to "...fulfil my duties faithfully and conscientiously in accordance with the Constitution and the law...", and to "...dedicate my abilities to the service and welfare of the people of Ireland." The president's official residence and principal workplace is Áras an Uachtaráin in Phoenix Park, Dublin.
