The Amato Group, officially the Action Committee for European Democracy (ACED) was a group of high-level European politicians unofficially working on rewriting the Treaty establishing a Constitution for Europe into what became known as the Treaty of Lisbon following its rejection by French and Dutch voters.

The Treaty establishing a Constitution for Europe was an unratified international treaty intended to create a consolidated constitution for the European Union (EU). It would have replaced the existing European Union treaties with a single text, given legal force to the Charter of Fundamental Rights, and expanded qualified majority voting into policy areas which had previously been decided by unanimity among member states.
