John George Butcher, 1st Baron Danesfort QC (15 November 1853 – 30 June 1935), known as Sir John Butcher, Bt, between 1918 and 1924, was a British barrister and Conservative Party politician.
Butcher was the second son of the Most Reverend Samuel Butcher, Bishop of Meath, the grandson of Vice-Admiral Samuel Butcher (1770–1849), and the younger brother of Samuel Henry Butcher. His mother was Mary, daughter of John Leahy. He was educated at Marlborough College and Trinity College, Cambridge, and was called to the Bar, Lincoln's Inn, in 1878.
Butcher was Member of Parliament for York from 1892 to 1906 and from 1910 to 1923, in 1918 becoming the first Member of Parliament for York to be the sole parliamentary representative, as the constituency had previously had two MPs. He was made a Queen's Counsel in 1897, awarded the honorary freedom of the City of York in 1906 and created a baronet, of Danesfort in the County of Kerry, in 1918. In 1924 he was further honoured when he was elevated to the peerage as Baron Danesfort, of Danesfort in the County of Kerry.
Lord Danesfort married Alice Mary, daughter of J. E. L. Brandreth, in 1898. There were no children from the marriage. She died in June 1929. Lord Danesfort survived her by six years and died in June 1935, aged 81, at which time the baronetcy and barony became extinct.
