John More Dick Peddie (21 August 1853 – 10 March 1921) was a Scottish architect.
Peddie was the son of the architect and politician John Dick Peddie (1824–1891) and his wife Euphemia Lockhart More. Born in Edinburgh, he attended Edinburgh Academy, followed by two years at a school in Elberfeld, Germany. He enrolled at Edinburgh University, and was also articled to his father's office. He then worked in the office of George Gilbert Scott, and later made a Grand Tour in Europe.
In 1875, he joined his father's firm, Peddie and Kinnear, and in 1878 became a partner. Peddie senior retired in 1879 and entered Parliament as Liberal MP for Kilmarnock Burghs. The practice became known as Kinnear and Peddie, with Charles Kinnear as senior partner. The Peddie family incurred substantial debts following the failure of some of John Dick Peddie's business interests, and fraud committed by his uncle. In 1878, the City of Glasgow Bank also collapsed, leading to recession in Scotland. However, the practice continued to find work, with J M Dick Peddie's designs including the Bank of Scotland's George Street branch (1883–1884). Kinnear worked on the practice's major schemes during the early 1880s, including Longmore Hospital and Craiglockhart Hydropathic, but in 1884 he became Colonel of the Midlothian Coast Artillery Volunteers, and his role in the firm reduced. He died suddenly in 1894, and within a year or two Peddie had taken on George Washington Browne (1853–1939), with whom he had worked informally for some time, as a partner. Further work on bank branches included several outlets of the British Linen Bank. The practice was very successful, and lasted formally to 1907. Peddie adopted a more Beaux-Arts style in his works over these years.
