"He has many qualities which will make us stronger as a defensive unit and as a team," Arsenal manager Mikel Arteta told the club website.
"He has proved with Lille that he is a defender with many outstanding attributes and we are looking forward to watching him grow as an Arsenal player.”
Gabriel, who signed for Lille in January 2017, joins a defence that has also been bolstered by the return of William Saliba from his loan at St-Etienne.
