Frank Ocean -- I'm Changing My Name ... To Frank Ocean

Frank Ocean has made a drastic decision to legally change his name ... but fear not ... it's not a Prince-esque symbol.

Ocean -- whose real name is Christopher Edwin Breaux -- filed legal docs to officially change his name to Frank Ocean.

To make it official ... Frank has to plaster his intentions in a newspaper on 4 separate occasions -- once a week, 4 weeks in a row. The idea is that if he's using the name to defraud someone, potential victims can come forward and object in court.
