Earl of Abingdon is a title in the Peerage of England. It was created on 30 November 1682 for James Bertie, 5th Baron Norreys of Rycote. He was the eldest son of Montagu Bertie, 2nd Earl of Lindsey by his second marriage to Bridget, 4th Baroness Norreys de Rycote, and the younger half-brother of Robert Bertie, 3rd Earl of Lindsey (see the Earl of Lindsey and the Baron Willoughby de Eresby for earlier history of the Bertie family). His mother's family descended from Sir Henry Norris, who represented Berkshire and Oxfordshire in the House of Commons and served as Ambassador to France. In 1572 he was summoned by writ to Parliament as Lord Norreys de Rycote. He was succeeded by his grandson, the second Baron. In 1621 he was created Viscount Thame and Earl of Berkshire in the Peerage of England. He had no sons and on his death in 1624 the viscountcy and earldom became extinct. He was succeeded in the barony by his daughter Elizabeth, the third holder of the title. On her death the title passed to her daughter, the aforementioned Bridget, the fourth Baroness, second wife of the second Earl of Lindsey.
