South American records in athletics are the best marks set in an event by an athlete who competes for a member nation of Atletismo Sudamericano. The organisation is responsible for ratification and it analyses each record before approving it. Records may be set on any continent and at any competition, providing that the correct measures are in place (such as wind-gauges) to allow for a verifiable and legal mark.
