The one-year loan for Balerdi comes with an option for Marseille to buy the player in summer 2021.
But Balerdi, 21, struggled and has rarely featured for the Bundesliga giants, leading to this loan move.
He is Marseille’s second recruit of the market after they struck a deal for midfielder Pape Gueye.
Balerdi will be hoping to revive his career at OM and add to his two caps for Argentina leading into next year’s World Cup.
