Henry Charles Sirr (1764–1841) was an Anglo-Irish soldier, Town Major (police chief) of Dublin, extortioner, wine merchant and art collector. Sirr played a prominent role in suppressing the Irish republican Society of United Irishmen and their uprising of 1798. He is especially known for the fatal shooting of the United Irishmen leader Lord Edward FitzGerald, who Sirr alleged had been resisting arrest.
