Edwin Richard Wyndham-Quin, 3rd Earl of Dunraven and Mount-Earl KP PC (19 May 1812 – 6 October 1871) was a British peer, Member of Parliament, and archaeologist.

He was styled Viscount Adare from 1824 to 1850. The son of Windham Quin, 2nd Earl of Dunraven and Mount-Earl, he succeeded to the Earldom on the death of his father in 1850.

Along with George Petrie, Lord Dunraven is credited with "laying the foundations of a sound school of archaeology" in Ireland.

The third Earl of Dunraven and Mount-Earl in the peerage of Ireland, and first Baron Kenry of the United Kingdom (1812–1871), born 19 May 1812, in London, was only son of Windham Henry, second earl. His grandfather, Valentine Richard Quin (1752–1824), as a staunch supporter of the union, was recommended by Lord Cornwallis for a peerage, with the title of Baron Adare (31 July 1800) (Cornwallis Correspondence, ed. Ross, iii. 25). He was further created Viscount Mount-Earl in 1816, and Earl of Dunraven in 1822.

Wyndham-Quin was educated at Eton and at Trinity College, Dublin, graduating BA in 1833.

He converted to Roman Catholicism in 1855.

The third earl's father, Windham Henry Quin, second earl of Dunraven (1782–1850), assumed in 1815 the additional name of Wyndham in right of his wife. He represented Limerick county in the imperial parliament from 1806 to 1820, and was a representative peer of Ireland from 1839 till his death.

The third earl's mother, Caroline, was daughter and heiress of Thomas Wyndham of Dunraven Castle, Glamorganshire. She inherited from her father property in Gloucestershire, as well as the Wyndham estate in Glamorganshire; she died on 26 May 1870.

As Viscount Adare, he sat as the Conservative MP for Glamorganshire from the General Election in July 1837 to 1851. While in the House of Commons he became a supporter of Catholicism. His political activity largely aimed at safeguarding religious education in Ireland (Hansard, 3rd ser. lxxx. 1142–3). He became subsequently one of the commissioners of education in Ireland. He succeeded his father as third earl in the Irish peerage in 1850, and retired from the House of Commons next year.
