Sir William Grantham (1835–1911) was a British barrister, Member of Parliament for 12 years for successive areas which took in Croydon then, from 1886, High Court judge.

[3] As a judge he was seen as competent but with a weakness for commenting on cases in a way that brought him into conflict with various groups, a habit that eventually led to hints in the newspapers that he should retire.

[1] His tenure as a judge was mainly uncontroversial until 1906, when, co-determining petitions following the general election: for Bodmin, Maidstone and Great Yarmouth, he was seen as favouring the Conservatives.

[1] A censure motion was proposed in the House of Commons and led to a vigorous debate, but the government declined to take it further, possibly because of the precedent it would set.

[1] He died later that year, of pneumonia, in his house, 100 Eaton Square,[6] London, aged 76,[1] also possessed of Barcombe Place, near Lewes, East Sussex.
