Association Planète Mars (APM) is a non-profit French organization, established in 1999 in the wake of the 1998 Mars Society founding convention, to which Richard Heidmann, the APM founding chairman, participated.

APM constitutes the French chapter of The Mars Society. It shares the views and supports the actions of this organization, nevertheless taking into consideration, if necessary, their adaptation to the national and European cultural and political context. It keeps close relationship with the other European chapters, as well as with the French and the European Space Agencies.
