The International Academy of Sciences San Marino (Esperanto: Akademio Internacia de la Sciencoj San Marino, AIS) was a scientific association. It was established in 1983 and had its first convention, SUS 1, around New Year 1984 in the City of San Marino. After the Sammarinese skeleton law on higher education had been passed the academy was officially founded on 13 September 1985, in the presence of the Captains-Regent. Its name uses the constructed international auxiliary language Esperanto. The association was dissolved at the end of 2020.
