The American Association of Engineering Societies (AAES) is a former umbrella organization of engineering societies in the United States, founded by a group of 43 societies in 1979. After several disputes, and a change in focus in the mid-1980s from speaking for the societies to coordinating between the societies, its membership was reduced to 22 societies by 1993, and 17 societies . The AAES dissolved in 2020.
