The title Earl Fife was a title in the Peerage of Ireland created by letters patent dated 26 April 1759 for William Duff (1696–1763) after (asserting but not proving) his descent from Macduff, the medieval Earl of Fife. Though in the Irish peerage, the title implies a connection with Fife in Scotland.

William Duff, 1st Earl Fife, had previously been created Baron Braco, of Kilbryde in the County of Cavan, in 1735, and was created Viscount Macduff at the same time as being raised to the Earldom. Both of these junior titles, though also in the Peerage of Ireland, also referred to places in Scotland, namely Braco and Macduff in Banffshire.

Between 1790 and 1885, the Earls Fife received several additional titles in the Peerage of Great Britain and of the United Kingdom, respectively, which allowed them to sit and vote in the House of Lords: In 1790 the 2nd Earl was created Baron Fife, of the County of Fife, in the Peerage of Great Britain, but this title became extinct on his death in 1809. The 4th Earl was also created Baron Fife, of the County of Fife, in the Peerage of the United Kingdom, in 1827, but again this title became extinct on his death in 1857. The 5th Earl was created Baron Skene, of Skene in the County of Aberdeen, in the Peerage of the United Kingdom, later that year. In 1885, the 6th Earl was created Earl of Fife in the Peerage of the United Kingdom.

In 1889, the 6th Earl Fife was further created Duke of Fife, in Scotland, and Marquess of Macduff, in the County of Banff, in the Peerage of the United Kingdom, two days after his marriage to Princess Louise of Wales, the eldest daughter of Albert Edward, Prince of Wales (the future King Edward VII). When it became clear that he would have no sons, he was further created Duke of Fife and Earl of Macduff, in the County of Banff, also in the Peerage of the United Kingdom, with a special remainder to his daughters and their heirs male.
