John Hosack (baptised 1813 – 1887)[1] was a Scottish lawyer and historical writer.
He was the third son of John R. Hosack of Glenaher, Dumfriesshire. He became a student of the Middle Temple in 1838, was called to the bar in 1841, and practised on the northern circuit and at the Liverpool sessions.[2]
In 1875, though not a Q.C., Hosack was made a bencher of his inn, and in 1877 he became police magistrate at Clerkenwell. He died at his house in Finborough Road, West Brompton, on 3 November 1887, and was buried at Lytham in Lancashire.[2]
