The Initiative for the Study of Asian Catholics (ISAC) is an international collaboration to foster social scientific research on Asian Catholics in contemporary societies. With the aim of facilitating dialogue, generating new research projects, and contributing to already existing research in the Philippines, Hong Kong, India, and other places, ISAC intends to expand and deepen conversations investigating the lived realities, socio-cultural contributions, and challenges faced by Asian Catholics at the local, national, and global levels.  While ISAC takes a multidisciplinary approach, it particularly encourages research on contemporary Asian Catholics from the perspectives of sociology, economy, environmental studies, anthropology, political sciences, art, gender studies, etc.

From 1 October 2021 to 8 December 2025 (Phase 1), ISAC was hosted by the Asia Research Institute, National University of Singapore, and is now undergoing a transition.
