This is an incomplete list of chess players who have represented more than one nation in FIDE-sanctioned tournaments. These players underwent a change in national federation affiliation but may not necessarily changed their citizenship in the process but may have to satisfy residency requirements. This excludes players which did not compete in any FIDE-sanctioned event for their previous federation.
