Henry Thring, 1st Baron Thring KCB (3 November 1818 – 4 February 1907), was a British lawyer and civil servant.
Henry was born in Alford, Somerset to Rev John Gale Dalton Thring (1784–1874), the Rector of Alford and later rural Dean for Cary; and Sarah née Jenkyns (1791–1891).
Thring was appointed First Parliamentary Counsel when that office was established in 1869, a position he held until 1901. He became known for his role as a parliamentary draftsman and as an innovator in the framing of legislation. Thring was appointed a Companion of the Order of the Bath (CB) in 1872, and promoted to Knight Commander (KCB) in 1873. In 1886 he was raised to the peerage as Baron Thring, of Alderhurst in the County of Surrey. He was a regular contributor in the House of Lords until 1905. Apart from his career in parliament he also served on the Council of the Royal College of Music.
He married Elizabeth née Cardwell (1822–1897) in 1856; they had one daughter, the Hon Katharine Annie Thring (1861–1947) who did not marry.
Lord Thring died in February 1907, aged 88, when the barony became extinct.
