Sir Joseph Walton (25 September 1845 – 12 August 1910) was an English lawyer and judge.

In the same year he entered Lincoln's Inn, where he was called to the bar on 17 November 1868, and was made a bencher in 1896.

Having succeeded Sir Charles Russell as leading counsel to the Jockey Club, he appeared in Powell v. Kempton Park Racecourse Company [1899] AC 143, which defined a "place" within the meaning of the Betting Act, 1853, and in the copyright case of Walter v. Lane [1900] AC 539, arising out of the republication of reports from The Times of speeches by Lord Rosebery which decided that there is copyright in the report of a speech.

At the same time, he became the dominant lawyer in the new Commercial Court, which had been established within the Queen's Bench Division in 1895.

[1] Upon the appointment in 1901 of Sir James Mathew to be a Lord Justice of Appeal, Walton succeeded him as a judge of the King's Bench Division of the High Court, and was knighted.

He died suddenly at his country residence at Shingle Street, near Woodbridge, on 12 August 1910, having taken, in the previous week, an active part in the proceedings of the International Law Association in London.

Walton took an active part in Catholic social and educational movements, and for a time was a member of the Liverpool school board.

A younger son, Louis Alban, second lieutenant, royal Lancaster regiment, died of enteric fever at Naauwpoort on 19 May 1901, aged twenty.

[2] According to a modern assessment:Walton never managed as a Judge to fulfil the expectations which he been generated by his career at the Bar.
