The 23-year-old signed for Newcastle last summer, but struggled for game time with the Magpies and was loaned back to Marseille in the second half of the season.
Now Marseille have captured Thauvin on loan once again and will have to make the deal permanent after the year's loan.
Thauvin is a former France U-21 international and played 10 matches, scoring six goals for France's U-21 side.
