The Société Française d'Astronomie et d'Astrophysique (SF2A) is a French society of professional astronomers.
The main goal of the society is the promotion of astronomy in France, associating to it the specialists of the field.
The society also represent France in the International Astronomical Union.
Each year the SF2A awards a scientific prize to a junior researcher, who must be younger than 36 and who must hold a permanent research position; and a prize for the best doctoral thesis in astronomy (defended in France, during the previous year).
An annual meeting is organized that supports the communication of recent research results by young astronomers, the debate of more political issues related to astronomy, and the gathering of the various members of the French astronomical community.
