The Nassau Grouper is found from Bermuda and Florida throughout the Bahamas and Caribbean Sea. Heemstra and Randall (1993) indicate a second subpopulation lying along the coast of Brazil, roughly from Forteleza to Rio de Janeiro. However this may be an error, as there do not appear to be any specimens or verifiable photographs of the Nassau grouper from Brazil (Heemstra, pers. comm. 2001, Moura 2001).
