Sydney John Chaplin (born Sydney John Hill; 16 March 1885 – 16 April 1965) was an English actor. Chaplin was the elder half-brother of actor and director Charlie Chaplin and served as his business manager in later life. Through their mother Hannah, they were older half-brothers to the younger Wheeler Dryden, who grew up separately with his father in England and was not told about his brothers until 1915. Dryden later immigrated to the United States, joining the Chaplins in Hollywood. Sydney Chaplin was also a half-uncle of actor Sydney Chaplin (1926–2009), who was named after him.
