The Gerontological Society of America (GSA) is a multidisciplinary organization devoted to research and education in all aspects of gerontology: medical, biological, psychological and social.

The Gerontological Society of America (GSA) was incorporated in New York City in 1945 as an outgrowth of a group of scientists and physicians who had been calling themselves "the Club for Research on Ageing" since the 1930s. GSA has been holding scientific conferences since 1946.

In 1969, GSA moved its main office from St. Louis, Missouri to Washington, D.C. The Gerontological Society of America, along with the American Geriatrics Society advocated for the formation of a National Gerontological Institute. These efforts bore fruit in 1974 when President Richard Nixon signed legislation to create the National Institute on Aging (NIA).

In 1946, GSA began publishing Journal of Gerontology.

In 1961, material in Journal of Gerontology dealing with GSA organization and activities was moved to a new journal called The Gerontologist.

In 1988, Journal of Gerontology was renamed Journals of Gerontology to reflect the fact that it was a composite of four journals having four separate editors.

In 1995, the four journals being published under one cover were split into two magazines ("two covers"): (1) the Journals of Gerontology: Biological Sciences and Medical Sciences and (2) the Journals of Gerontology: Psychological Sciences and Social Sciences. Also in 1995 GSA began publishing The Public Policy and Aging Report to deal specifically with policy issues, and directed to those outside as well as within the academic community.

The primary activities of GSA are to:
