Llewellyn Archer Atherley-Jones QC (1851 – 15 June 1929) was a radical British Liberal Party politician and Barrister who eventually became a judge.
Atherley-Jones was the son of Ernest Jones, a prominent Chartist leader who was also a Barrister (who adopted a hyphenated surname to include his mother's maiden name) and Jane Barfield of Cumberland.
He was chosen as candidate for Ealing in 1884, but as the election approached, had a much better offer from North West Durham which was an area with a large number of miners and where a Liberal victory was much more likely.
At his eighth and last General Election contest, in December 1910, he was comfortably re-elected again; In 1913 he resigned his seat as he was appointed a Judge of the City of London Court.
As a judge at the Old Bailey in the 1920s, he acquired a reputation for dealing sympathetically with men charged with consensual homosexual offences.
