Sir William Flood Webb KBE (21 January 1887 – 11 August 1972) was an Australian lawyer.

He was appointed President of the International Military Tribunal for the Far East by General Douglas MacArthur, commonly known as the Tokyo trial, after the end of World War II.

On 27 June 1940 he was promoted to Chief Justice of Queensland, an office he held until 15 May 1946, when he left to take a seat on the High Court of Australia.

[1] He also visited London in 1944 to give advice on his reports to the United Nations War Crimes Commission.

Webb was involved in a minor scandal late in 1947, in the leadup to the bank nationalisation case, the Government of Australia tried to recall Webb from Tokyo, by requesting General Douglas MacArthur to release him, because they believed that he would decide the case in a way that was favourable to the Commonwealth.
