Earl of Selborne, in the County of Southampton, is a title in the Peerage of the United Kingdom. It was created in 1882 for the lawyer and Liberal politician Roundell Palmer, 1st Baron Selborne, along with the subsidiary title of Viscount Wolmer, of Blackmoor in the County of Southampton. He had already been made Baron Selborne, of Selborne in the County of Southampton, in 1872, also in the Peerage of the United Kingdom. Both his son, the second Earl, and grandson, the third Earl, were prominent Liberal Unionist politicians. The latter was in 1941 called to the House of Lords through a writ of acceleration in his father's barony of Selborne. As of 2009 the titles are held by the third Earl's grandson, the fourth Earl. He is one of the ninety elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999, and sits as a Conservative.
The family seat is Temple Manor, near Selborne, Hampshire.
