The Linguasphere Observatory (or "Observatoire", based upon its original French and legal title: ) is a transnational linguistic research network. 

It was created in Quebec in 1983 and was subsequently established and registered in Normandy as a non-profit association under the honorary presidency of the late Léopold Sédar Senghor, a French-language poet and the first president of Senegal. Its founding director is David Dalby, former director of the International African Institute and emeritus reader in the University of London, and its first research secretary was Philippe Blanchet, a Provençal-language poet currently serving as Professor of Sociolinguistics at the University of Rennes. Since 2010, the deputy director and webmaster of the Observatoire has been Pierrick le Feuvre,with the chairman of its research council being Roland Breton, emeritus professor at the University of Paris VIII. The Observatoire's research hub is currently based in the European Union, in Carmarthenshire, Wales (UK) and in Paris. Its title in Welsh is Wylfa Ieithoedd, literally the "Observatory (of) languages", and its publishing associate (also in Wales) is the Gwasg y Byd Iaith, i.e., "Linguasphere Press" or literally "Press (of) the world (of) language". 

The Observatoire has developed an innovative scheme of philological classification, coding all living and recorded languages within a global referential framework or "linguascale". This Linguascale Framework uses a decimal structure (see below) to record both genetic and geographic categories of relationship (termed "phylozones" and "geozones", respectively).
