The International Society on General Relativity and Gravitation (ISGRG) is a learned society established in 1971 with the goal to promote research on general relativity (GR) and gravitation. To that end, it encourages communication between relativity researchers, in particular by organizing the triennial international GR conferences, sponsoring the Hyperspace website, and publishing the journal General Relativity and Gravitation. The society also serves as the Affiliated Commission 2 (AC.2) of the International Union of Pure and Applied Physics.
