Stewart Kyd (born 1759, died 26 January 1811) was a Scottish politician and legal writer.
A native of Arbroath, Forfarshire, he went at the age of fourteen from Arbroath grammar school to King's College, Aberdeen. Abandoning a design of entering the church, he settled in London, and was called to the bar from the Middle Temple. He became a friend of Thomas Hardy and John Horne Tooke, whose political opinions he admired. In November 1792 he joined the Society for Constitutional Information.
On 29 May 1794 he was arrested and examined by the privy counsel but was soon discharged. On 4 June he was again summoned before the counsel, and three days later was committed to the Tower on a charge of high treason, with Hardy, Tooke, and ten others. On 25 October all the prisoners were brought up for trial before a special commission at the Old Bailey, but after the acquittal of Hardy, Tooke and John Thelwall, the attorney-general declined offering any evidence against Kyd, and he was discharged.
In June 1797 he defended Thomas Williams, a bookseller, who was indicted for blasphemy in publishing Tom Paine's The Age of Reason. His speech was printed during the same year. Kyd died in the Temple on 26 January 1811. His portrait has been engraved.
