Baron Ebury, of Ebury Manor in the County of Middlesex, is a title in the Peerage of the United Kingdom that dates from 1857. In 1999, it became a subsidiary title of the earldom of Wilton after the 6th Baron Ebury inherited the earldom from his distant cousin, the 7th Earl of Wilton.
The peerage was created in September 1857 for the Whig politician Lord Robert Grosvenor. He was the third son of Robert Grosvenor, 1st Marquess of Westminster, and his wife Lady Eleanor Egerton, daughter of Thomas Egerton, 1st Earl of Wilton.
Both Lord Robert and his elder brother Lord Thomas were in special remainder to the viscountcy of Grey de Wilton and the earldom of Wilton, created for their maternal grandfather in 1801. Upon the latter's death in 1814, Lord Thomas succeeded as second Earl of Wilton.
Lord Ebury was succeeded by his eldest son, the second Baron. He represented Westminster in Parliament as a Liberal. His grandson, the fifth Baron, served as a government whip from 1939 to 1940 in the government of Neville Chamberlain. In 1999, his eldest son, the sixth Baron, succeeded as eighth Earl of Wilton on the death of his kinsman, the seventh Earl.
The Honourable Norman Grosvenor, younger son of the first Baron, sat as Member of Parliament for Chester.
