The Glynne Baronetcy, of Bicester in the County of Oxford, was a title in the Baronetage of England. It was created on 20 May 1661 for William Glynne, the former Member of Parliament for Carnarvon. He was the son of Sir John Glynne, Lord Chief Justice during the Commonwealth. The second Baronet sat as Member of Parliament for Oxford University and Woodstock. The sixth Baronet was Member of Parliament for Flintshire and Flint. The title became extinct on the death in 1874 of Sir Stephen Glynne, 9th Baronet. The family estates, including Hawarden CastleinFlintshire, had been rescued from bankruptcy by the wealth of Sir John Gladstone, whose son William Ewart Gladstone (the Liberal Prime Minister) had married the ninth Baronet's sister Catherine; on his death, they passed to Catherine and William's eldest son William Henry Gladstone.
