Wotton Underwood is a village and civil parish in Buckinghamshire, England, 7 miles (11 km) north of Thame, Oxfordshire.

Wotton House, Wotton Underwood, Buckinghamshire, England, is a stately home built between 1704 and 1714, to a design very similar to that of the contemporary version of Buckingham House. The house is an example of English Baroque and a Grade I listed building. The architect is uncertain although William Winde, the designer of Buckingham House, has been suggested. The grounds were laid out by George London and Henry Wise with a formal parterre and a double elm avenue leading down to a lake. Fifty years later William Pitt the Elder and Capability Brown improved the landscape, creating pleasure grounds with two lakes. After a fire gutted the main house in 1820 Richard Grenville, 1st Earl Temple, commissioned John Soane to rebuild it. After the 3rd Duke of Buckingham and Chandos, the last direct Grenville male heir, died in 1889, the house was let to a succession of tenants; including, notably; the philanthropist, Leo Bernard William Bonn (1850-1929) who became deaf while residing at Wotton, and later founded (1911) what became the RNID. His son and heir, the decorated First World War hero, Major Walter Basil Louis Bonn, DSO, MC, MA (Oxon.) FRSA, FZSL (1885-1973) is also listed as resident at Wotton House; in the New College archives, at Oxford University; during his three years as an Oxford undergraduate, there, 1903–1906, while living fifteen miles away from his family home of many years, at Wotton House.
