Sir John Arnold Wallinger (25 October 1869 – 7 January 1931) was a British Indian intelligence officer who led the prototype Indian Political Intelligence Office from 1909 to 1916. He was also the literary prototype of the spymaster of a number of Somerset Maugham's short stories. Wallinger is credited with leading the Indian intelligence missions outside India, notably against the Indian Anarchist movement in England, and later against the Berlin Committee and the Hindu-German Conspiracy during World War I. Among his more famous agents was Somerset Maugham who was recruited as a British agent in Switzerland.
