Centre de Liaison et d'Information des Puissances maçonniques Signataires de l'Appel de Strasbourg

CLIPSAS (Centre de Liaison et d'Information des Puissances maçonniques Signataires de l'Appel de Strasbourg; English: "Liaison and Information Center of Masonic Powers Signatories of the Strasbourg Appeal") is an international Masonic organization that serves as the primary coordinating body for Liberal and Adogmatic Freemasonry worldwide. Established in 1961 through the historic Strasbourg Appeal, CLIPSAS represents an alternative to Conservative Anglo-Saxon Masonic recognition systems, emphasizing absolute freedom of conscience and inclusive Masonic practices.

The organization maintains observer status at the United Nations Economic and Social Council (ECOSOC) and comprises over 100 member obediences across multiple continents. CLIPSAS is distinguished by its recognition of masculine, feminine, and mixed-gender Masonic bodies, as well as its philosophical stance that religious belief should not be a prerequisite for Masonic membership.
