Amine Harit and Amine Gouiri scored in the first half to give Marseille all three points in their Matchday 9 encounter.
The hosts made a flying start, taking the lead after just one minute when Harit found the net, with Gouiri providing the assist.
Marseille doubled their advantage in the 25th minute as Gouiri finished off a move created by Igor Paixão to make it 2-0.
Toulouse attempted to respond and enjoyed more possession as the match progressed, but Marseille defended their advantage effectively.
Goalkeeper Jeffrey De Lange also played an important role in preserving the clean sheet, producing key saves to frustrate the visitors.
Toulouse thought they had pulled a goal back through Casper Tengstedt in the 68th minute, but the effort was ruled out for offside.
Marseille managed the closing stages comfortably to secure their fourth consecutive Ligue 1 victory.
The result represents a significant turnaround for the French giants, who had previously suffered four successive league defeats. They have now climbed to sixth place in the standings.
Marseille will look to maintain their momentum in their next league fixture, while Toulouse must regroup after failing to take advantage of their possession and attacking opportunities.
