Baron Denham, of Weston Underwood in the County of Buckingham, is a title in the Peerage of the United Kingdom. It was created in 1937 for Sir George Bowyer, 1st Baronet, a Conservative politician who had earlier represented Buckingham in the House of Commons. He had already been created a baronet, of Weston Underwood, in 1933. Bowyer was a great-great-great-grandson of Sir William Bowyer, 3rd Baronet, of Denham Court (see below). As of 2017^[update] the titles are held by his second but only surviving son, the 2nd Baron, who succeeded in 1948. In 1950 he also succeeded his distant relative in the Bowyer baronetcy, of Denham Court. Like his father, the 2nd Baron Denham was a Conservative politician and one of the ninety elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999.

The Bowyer baronetcy, of Denham Court in the County of Buckingham, was created in the Baronetage of England in 1660 for William Bowyer. He represented Buckinghamshire in the House of Commons.

His great-great-grandson Sir George Bowyer, the 5th Baronet, was an Admiral in the Royal Navy and distinguished himself at the Battle of the Glorious First of June in 1794. For this he was created a baronet, of Radley in the County of Berkshire, in his own right. In 1799 he also succeeded his elder brother in the baronetcy of Denham Court. His son, the 6th and 2nd Baronet, sat as Member of Parliament for Malmesbury and Abingdon. He was succeeded by his son, the 7th and 3rd Baronet, who represented Dundalk and County Wexford in Parliament as a Liberal. On the death in 1950 of his nephew, the 9th and 5th Baronet, the baronetcy of Radley became extinct. The late Baronet was succeeded in the baronetcy of Denham Court by his distant relative the 2nd Baron Denham, 2nd Baronet, of Weston Underwood (see above), who became the 10th Baronet. The titles remain united.

The family seat is The Laundry Cottage, near Weston Underwood, Buckinghamshire.
