Paris St-Germain claimed their eighth Ligue 1 title without kicking a ball after second-placed Lille were held to a goalless draw at Toulouse.
The leaders have 81 points after 32 games and cannot be caught as they lead Lille, who have played one more match, by 16 points with five games remaining.
Thomas Tuchel's side will take to the field as champions when they host Monaco later on Sunday.
PSG have now won the title six times in the past seven seasons.
The Parisians could win the domestic double when they face Stade Rennais in the French Cup final next Saturday.
