Marseille hit back to level five minutes later through Andre-Pierre Gignac.
Both sides were reduced to ten men ten minutes from time when Abdelhamid El Kaoutari was sent off for bringing down Loic Remy for a penalty with the Marseille striker also seeing red for slapping the Montpellier man.
Taye Taiwo kept his cool from the penalty spot to give Marseille all three points and keep alive their hopes of retaining the title.
Valenciennes condemned
Arles to relegation with a 1-0 win.
Gregory Pujol's second-half strike earned Valenciennes all three points to send Arles back to Ligue 2 after just one season in the top flight.

Lyon's title hopes with a 1-0 at Parc des Princes.
Zoumana Camara scored the only goal of the game 13 minutes from time to move PSG up to fourth and leave Lyon six points behind leaders Lille.
