The Archaeological Institute of America (AIA) is a North American nonprofit organization devoted to the promotion of public interest in archaeology, and the preservation of archaeological sites. It has offices on the campus of Boston University and in New York City.
The institute was founded in 1879, with Charles Eliot Norton as its first President until 1890. It was chartered in 1906 by the United States Congress. The institute currently has over 200,000 members and more than 100 local societies.
The American Journal of Archaeology, AJA, is the AIA's peer-reviewed academic journal that appears four times each year. The institute has also been publishing the magazine Archaeology since 1948.
