The FIA CODASUR Rally Championship is an international rally championship which is run by Confederacion Deportiva Automovilismo Sudamericana (CODASUR) under the auspices of the FIA and held across South America, although some events in the northernmost reaches of South America compete in the NACAM Rally Championship zone rather than Codasur.

Paraguayan Gustavo Saba is the most successful in Codasur history with three consecutive titles from 2011 to 2013 and another three from 2016 to 2018.
