The 23rd International Conference on General Relativity and Gravitation (GR23) and the 2022 annual meeting of the Division of Gravitation and Relativistic Astrophysics, Chinese Physical Society, were successfully held in Liyang, China, from July 3 to 8, 2022. GR23 was hosted by the Institute of Theoretical Physics, Chinese Academy of Sciences (CAS). Organizational support was provided by Beijing Normal University, Hangzhou Institute for Advanced Study of UCAS, Huazhong University of Science and Technology, Hunan Normal University, Jilin University, Lanzhou University, Shanghai University, Sun Yat-sen University, Tianjin University, University of CAS, Yangzhou University, Zhejiang University of Technology, Universe (ISSN 2218-1997, Published by MDPI), the Division of Gravitation and Relativistic Astrophysics of the Chinese Physical Society, the International Union of Pure and Applied Physics (IUPAP), the Chinese Academy of Sciences, and the National Natural Science Foundation of China. Due to COVID-19, GR23 was held as a hybrid conference, with online and onsite components.

GR23 is the latest in the series of triennial international conferences held under the auspices of the International Society on General Relativity and Gravitation (ISFRG). The conference series constitutes the principal international meetings for scientists working in all areas of relativity and gravitation. GR23 was attended, in terms of both online and onsite participants, by more than 1100 scholars from 52 countries and regions in the world. Seventeen plenary speakers and 386 parallel speakers discussed aspects of the recent progress that has been made in relativity and gravitation. Professor Adam Riess from Johns Hopkins University, who was awarded the 2011 Novel Prize in physics, gave a public lecture titled “Surprises from the Expansion of the Universe.”

Professor Nils Andersson, the ISGRG President, chaired the awards ceremony. There was a brief presentation of the two 2022 thesis prizes, i.e., the Jürgen Ehlers Prize in areas of mathematical and numerical general relativity, and the Bergmann-Wheeler Prize, which encompasses a broad area that includes all approaches to quantum gravity. This presentation was followed by three talks from the IUPAP Early Career Award winners of 2020–2022, who are Davide Gerosa from the University of Milano-Bicocca, Christopher Berry from the University of Glasgow, and Katerina Chatziioannou from Caltech.

At the ISGRG General Assembly, the new ISGRG Fellows were announced. The 2022 ISGRG Fellows are Beverly Berger, Robert Caldwell, Roberto Emparan, John Friedman, Malcolm Maccallum, Mukund Rangamani, Harvey Reall, Luciano Rezzolla, Sheila Rowan, Susan Scott, and Matt Visser. Moreover, it was announced that GR24 will be hosted by the University of Glasgow, UK.
