Sir John William Salmond KC (3 December 1862 – 19 September 1924) was a legal scholar, public servant and judge in New Zealand.

He then obtained a Gilchrist scholarship to study at University College, London, where he graduated in law and became a fellow.

Returning to New Zealand in 1887, he was admitted as a barrister and solicitor of the Supreme Court, and practised in Temuka in South Canterbury.

Upon his return to New Zealand he resumed his judicial duties but died, following a heart attack, in Wellington, and was buried in Karori Cemetery.

They had two sons and a daughter, of whom the eldest, Captain William Guthrie Salmond, was killed in action in France in July 1918.
