Marquess of Buckingham was a title that has been created two times in the peerages of England and Great Britain.

The first creation of the marquessate was in 1618 for George Villiers, a favourite of James I of England. He had previously been made Baron Whaddon, of Whaddon in the County of Buckingham, and Viscount Villiers in 1616, then Earl of Buckingham in 1617. Later he was also created Earl of Coventry and Duke of Buckingham in 1623. With his son's death in 1687, the title became extinct.

The second creation came in 1784, when George Nugent-Temple-Grenville, 3rd Earl Temple was made Marquess of Buckingham in the Peerage of Great Britain. However, on his grandson's death in 1889 without male issue, the marquessate of Buckingham became extinct.
