The National Academies of Sciences, Engineering, and Medicine (also known as NASEM or the National Academies) is a congressionally chartered organization that serves as the collective scientific national academy of the United States. The name is used interchangeably in two senses: (1) as an umbrella term or parent organization for its three sub-divisions that operate as quasi-independent honorific learned society member organizations known as the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the National Academy of Medicine (NAM); and (2) as the brand for studies and reports issued by the unified operating arm of the three academies originally known as the National Research Council (NRC). The National Academies also serve as public policy advisors, research institutes, think tanks, and public administration consultants on issues of public importance or on request by the government.The National Research Council, National Academy of Engineering, and National Academy of Medicine began as activities of the National Academy of Sciences until they were reorganized in 2015 into units of the current National Academies while maintaining the charter status and corporate successorship of the original National Academy of Sciences. Now jointly governed by all three academies, the NRC produces some 200 publications annually which are published by the National Academies Press. The reports produced by the National Academies have been characterized as reflective of scientific consensus.

The National Academy of Medicine (NAM), known as the Institute of Medicine (IoM) until 2015, is an American nonprofit, non-governmental organization. The National Academy of Medicine is a part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Sciences (NAS), National Academy of Engineering (NAE), and the National Research Council (NRC). The National Academy of Medicine provides national and international advice on issues relating to health, medicine, health policy, and biomedical science. It aims to provide unbiased, evidence-based, and authoritative information and advice concerning health and science policy to policy-makers, professionals, leaders in every sector of society, and the public at large. Operating outside the framework of the U.S. federal government, it relies on a volunteer workforce of scientists and other experts, operating under a formal peer-review system. As a national academy, the organization annually elects new members with the help of its current members; the election is based on the members' distinguished and continuing achievements in a relevant field as well as for their willingness to participate actively.
