The European Astronomical Society (EAS) is a learned society, founded under the Swiss Civil Code in 1990, as an association to contribute and promote the advancement of astronomy in Europe, and to deal with astronomical matters at a European level.

The President of the European Astronomical Society chairs the governing Council of the EAS and liaises with similar societies in countries around the world, and with the International Astronomical Union on behalf of the European astronomy community.

The first person to hold the title of President of the European Astronomical Society was Lodewijk Woltjer, a post he held from the founding of the EAS until 1994.

Thierry Courvoisier [fr] and Roger Davies are the only holders to have been re-elected for a second term.

The European Astronomical Society awards several prizes on an annual or biannual basis.
