Viscount Doneraile (/ˈdʌnərəl/^{[citation needed]}) is a title that has been created twice in the Peerage of Ireland, both times for members of the St Leger family.

It was first created in 1703 for Arthur St Leger, along with the subsidiary title of Baron Kilmayden, also in the Peerage of Ireland. This creation became extinct in 1767 upon the death of the fourth Viscount. His daughter, Elizabeth, had a son named St Leger Aldworth, who succeeded to the Doneraile estates and assumed the surname of St Leger in lieu of his patronymic. He notably represented Doneraile in the Irish Parliament from 1749 to 1776. The latter year, he was raised to the Peerage of Ireland as Baron Doneraile. In 1785, the viscountcy was revived and he was created Viscount Doneraile, also in the Peerage of Ireland.

His grandson, the third Viscount, sat in the House of Lords as an Irish representative peer from 1830 to 1854. His son, the fourth Viscount, was an Irish Representative Peer between 1855 and 1887. He was succeeded by his second cousin, the fifth Viscount. His son, the sixth Viscount, served as Mayor of the City of Westminster.

On the death of his younger brother, the seventh Viscount, this line of the family failed, and he was succeeded by his second cousin once removed, the eighth Viscount. As of 2014^[update], the titles are held by the latter's grandson, the tenth Viscount, who succeeded his father in 1983. He lives in California.

The family seat was Doneraile Court, near Mallow, County Cork.
