The Asia-Pacific International Symposium on Aerospace Technology (APISAT) is a common endeavour among the four national aerospace societies in China, Australia, Korea and Japan, namely, Chinese Society of Aeronautics and Astronautics (CSAA), Royal Aeronautical Society Australian Division (RAeS Australian Division), Japan Society for Aeronautical and Space Sciences (JSASS) and Korean Society for Aeronautical and Space Sciences (KSAS).

APISAT is an annual event initiated in 2009. It aims to provide the opportunity to Asia-Pacific nations for the researchers of universities and academic institutes, and for the industry engineers to discuss the current and future advanced topics in aeronautical and space engineering.

Since 2009, it has been held by CSAA, RAeS Australian Division, JSASS and KSAS in turn. The APISAT2020 has been postponed to 2021 and carried out in hybrid.
