Baron Grimthorpe, of Grimthorpe in the East Riding of the County of York, is a title in the Peerage of the United Kingdom.^[1] It was created on 17 February 1886 for the lawyer and architect Edmund Beckett, 5th Baronet, with remainder to the heirs male of his father. He was succeeded according to the special remainder by his nephew, the second Baron. He had earlier represented Grimsby in Parliament. As of 2014^[update] the titles are held by the latter's great-grandson, the fifth Baron, who succeeded his father in 2003.

The Beckett baronetcy, of Leeds in the County of York, was created in the Baronetage of the United Kingdom in 1813 for John Beckett, Permanent Under-Secretary of State at the Home Office. His eldest son, the second Baronet, was a Tory politician. On his death the title passed to his younger brother, the third Baronet, and then to another brother, the fourth Baronet. The latter represented the West Riding of Yorkshire in Parliament. He was succeeded by his eldest son, the fifth Baronet, who was raised to the peerage as Baron Grimthorpe in 1886.

Another member of the Beckett family was the Conservative politician Gervase Beckett. He was the younger brother of the second Baron Grimthorpe.
