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.

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.

As of 2014[update], the titles are held by the latter's grandson, the tenth Viscount, who succeeded his father in 1983.
