Patrick Moylett (1878–1973) was a 20th-century Irish nationalist who, during the initial armistice negotiations to end the Anglo-Irish war, briefly served as president of the Irish Republican Brotherhood during late-1920. A successful businessman in County Mayo and County Galway, he was a close associate of Arthur Griffith and frequently travelled to London acting as a middleman between Sinn Féin and officials in the British government. He ran a business that was used as a front to import armaments for the cause and held that many of those that became closest associates of Éamon de Valera during the civil war rift had at one time worked for the British. Particularly that Erskine Childers despite his involvement with the Asgard and his close association with Éamon de Valera had been in the direct pay of the Admiralty Naval Intelligence Service up till 1916 before becoming secretary to the Éamon de Valera led treaty discussions.
