The Musée de la Franc-Maçonnerie (French pronunciation: [myze də la fʁɑ̃ masɔnʁi], Museum of Freemasonry) is a museum of Freemasonry located in the 9th arrondissement at 16, rue Cadet, Paris, France.

The museum was established in 1889 by the Grand Orient de France as a cabinet of curiosities in the Hotel Cadet.

In that same year, many of its historical documents were returned from Moscow, where they had been held by the KGB after Germany's defeat in World War II.

It has the support of the Ministry of Culture, the Île-de-France region and the town hall of Paris.
