The South African National Space Agency (SANSA) is South Africa's government agency responsible for the promotion and development of aeronautics and aerospace space research. It fosters cooperation in space-related activities and research in space science, seeks to advance scientific engineering through human capital, as well as the peaceful use of outer space, and supports the creation of an environment conducive to the industrial development of space technologies within the framework of national government.

SANSA was established on 9 December 2010 by the National Space Agency Act.

Currently, SANSA's main focusses include using data obtained from remote sensing through satellites and other projects to provide assessment on flooding, fires, resource management and environmental phenomena in South Africa and the African continent.
