Giuliano Amato (Italian pronunciation: [dʒuˈljaːno aˈmaːto]; born 13 May 1938) is an Italian politician who twice served as Prime Minister of Italy, first from 1992 to 1993 and again from 2000 to 2001.

Later, he was Vice President of the Convention on the Future of Europe that drafted the European Constitution and headed the Amato Group. He is commonly nicknamed dottor Sottile, which means "Doctor Subtilis", the sobriquet of the Scottish Medieval philosopher John Duns Scotus, a reference to his political subtlety. From 2006 to 2008, he was the Minister of the Interior in Romano Prodi's government.

He has served on the Constitutional Court of Italy from September 2013 to September 2022, to which he was appointed by President Giorgio Napolitano. He also served as President of the Court from 29 January 2022 to 18 September 2022.
