Baron Walsingham, of Walsingham in the County of Norfolk, is a title in the Peerage of Great Britain.
This noble title was created in 1780 for Sir William de Grey on his retirement as Lord Chief Justice, who had previously served as Solicitor-General and as Attorney-General. His son, the second Baron, represented Wareham, Tamworth and Lostwithiel in the House of Commons and served as Joint Postmaster-General from 1787 to 1794; Lord Walsingham was also Chairman of Committees in the House of Lords for many years. His eldest son, the third Baron, was a Lieutenant-General in the Army, who was succeeded by his younger brother, the Archdeacon of Surrey, as fourth Baron. His grandson, the sixth Baron, was a Conservative Member of Parliament for Norfolk West and served as a Government Whip from 1874 to 1875 in Benjamin Disraeli's second administration. On his death the title passed to his half-brother, the seventh Baron, a barrister.
