Charles James Blomfield (29 May 1786 – 5 August 1857) was a British divine, and a Church of England bishop for 32 years.
In 1828, he was appointed a Privy Counsellor and translated becoming bishop of London, a post which he held for twenty-eight years. During this period, his energy and zeal did much to extend the influence of the church. He was one of the best debaters in the House of Lords (members of the Upper House of the Canterbury Convocation confessed to trimming their quill pens before his arrival!), took a leading position in the action for church reform which culminated in the ecclesiastical commission, and did much for the extension of the colonial episcopate; and his genial and kindly nature made him an invaluable mediator in the controversies arising out of the tractarian movement.
Among other posts he was Bishop of London.
His health at last gave way, and in 1856 he was permitted to resign his bishopric, retaining Fulham Palace as his residence, with a pension of £6000 per annum.
Blomfield is buried in the churchyard of All Saints Church, Fulham, London and a memorial to him, by G. Richmond, can be seen at Saint Paul's Cathedral along the south wall of the ambulatory.
