Earl of Bandon was a title in the Peerage of Ireland. It was created in 1800 for Francis Bernard, 1st Viscount Bandon.^{[1][unreliable source?]} He had already been created Baron Bandon, of Bandon Bridge in the County of Cork, in 1793,^[2] Viscount Bandon, of Bandon Bridge in the County of Cork, in 1795,^[3] and was made Viscount Bernard at the same time as he was granted the earldom. These titles were also in the Peerage of Ireland. The titles descended from father to son until the death of his great-grandson, James, the fourth Earl, in 1924. The late Earl was succeeded by his first cousin twice removed, Percy Bernard, the fifth Earl. The latter was the great-grandson of the Right Reverend Charles Bernard, Bishop of Tuam, younger son of the second Earl. The fifth Earl was an Air Chief Marshal in the Royal Air Force. He had two daughters but no sons and on his death in 1979 the titles became extinct.

Francis Bernard, great-grandfather of the first Earl, was a lawyer and politician while Francis' younger brother Arthur is the 7th-great-grandfather of Justin Trudeau, Prime Minister of Canada.^[4][5] James Bernard, father of the first Earl, was a politician.

The family seat of the Earls of Bandon was Castle Bernard, County Cork, in the Republic of Ireland. Castle Bernard itself was destroyed as a result of an IRA attack in 1921 and now stands as a ruin. The family later built a new home on the estate, which remained in the ownership of Lady Jennifer Bernard (1935–2010), the elder daughter of the late 5th and last Earl of Bandon by his first wife, until her death. The Castle Bernard estate is currently (2011) owned by Lady Frances Carter (b. 1943), the younger sister of the late Lady Jennifer Bernard.
