The Musée aéronautique et spatial Safran is a French private aviation museum located in Melun, Seine-et-Marne. Established in May 1989 the museum contains a large collection of historic and modern aircraft engines. These engines have been produced by various French engine manufacturers such as Gnome et Rhône and Snecma which are now part of the present day Safran company. The latter is the creator and manager of the museum.

The main exhibits are piston engines and turbojets that powered aircraft as well as rocket engines used for aircraft and spacecraft. All the exhibits were developed and produced by companies that were eventually merged into the Safran group.
