Operation Hush was a British plan to make amphibious landings on the Belgian coast in 1917 during the First World War, supported by an attack from Nieuwpoort and the Yser bridgehead, positions which were a legacy of the Battle of the Yser in 1914. Several plans were considered in 1915 and 1916, then shelved due to operations elsewhere. Operation Hush was intended to begin when the Third Battle of Ypres, the main offensive at Ypres had advanced to Roulers, Koekelare and Thourout, linked by advances by the French and Belgian armies in between.
