The Asian Society for Neuroanesthesia and Critical Care (ASNACC) is a non-profit, scientific organization whose main thrust is the exchange of information in the fields of neurosciences, neuroanesthesia, and neurocritical care among its members in Asia. It was created following a proposal by Haekyu Kim from South Korea in 2004 during the 1st China-Japan-Korea Joint Symposium for Neuroanesthesia. The founding member countries include South Korea, Japan, China, India, Indonesia, and Singapore. The Philippines, Malaysia, Thailand, and Myanmar joined thereafter. The first Congress of ASNACC was held in Beijing, China in 2006, and has been a biennial event, the last being held in Nara, Japan in 2019.

The members comprise doctors from the fields of neuroanesthesiology and critical care. The goals of the Society include enhancing abilities in clinical practice in the field of neuroanesthesia and neurocritical care, enhancing research abilities in the field of neuroscience in Asia, and importantly to establish a forum for exchange of view among its members.
