The ALMA Board, a supervisory and regulatory body for ALMA, is composed of representatives of three funding Parties: the National Institutes of Natural Sciences (NINS) of Japan; the European Southern Observatory (ESO); and the U.S. National Science Foundation (NSF), and representatives of the three Executives: the National astronomical Observatory of Japan (NAOJ); ESO, and Associated Universities, Inc. (AUI) / the National Radio Astronomy Observatory (NRAO); and representatives of regional user communities.

Current ALMA Board members can be found on the JAO website.

The Director’s Council was a body established by the ALMA Agreement as a forum to discuss and coordinate activities among the Executives (NAOJ, ESO, and NRAO) and the Joint ALMA Observatory (JAO). The Director’s Council shall actively address any issues where any decisions or actions made by the Executive(s) or the JAO might have an impact on proper functions of ALMA (e.g. scientific/technical operations, human resources, management, education and public outreach, relations with Chile, etc.)

Current Director's Council members are:
- Director General, National Astronomical Observatory of Japan
- Director General, European Southern Observatory
- Director, National Radio Astronomy Observatory
- ALMA Director

While the ALMA Board is the governing body and primary forum of the ALMA Project to ensure the joint operations of ALMA in a global partnership, there are external (independent) advisory committees to discuss specific matters regarding science, technology, human resources, finance, and administration, etc. Each advisory committee addresses a wide variety of issues from a viewpoint of the entire ALMA Project as well as from the regional viewpoint considering respective Executive’s circumstances.
