John Wallace Riddle Jr. (July 12, 1864 – December 8, 1941) was an American diplomat. His first diplomatic assignment was as agent/consul general in Egypt (1904–1905). He was then sent to Romania and Serbia in 1905 to serve as Envoy Extraordinary and Minister Plenipotentiary (residing in Bucharest), followed by postings as U.S. ambassador to Russia (1907–1909) and ambassador to Argentina (1922–1925).
Riddle was the son of John Wallace Riddle, Sr. and Rebecca Blair McClure; he was born after his father's untimely death. A few years later, Rebecca McClure became the second wife of Charles Eugene Flandrau and relocated to St. Paul, Minnesota where Riddle grew up alongside two half-brothers and two step-sisters. He graduated from Harvard in 1887, attended law school at Columbia through 1890, and studied international law, diplomacy, and languages at École Libre des Sciences Politiques and the Collège de France in Paris through 1893.
