The 2011 World Player of the Year, who was sidelined earlier this year with badly sprained ligaments in his right knee, will take over the reins from lock Pascal Pape.
Coach Philippe Saint-Andre confirmed the switch on Friday when unveiling a 30-strong training squad for the Autumn Tests against New Zealand, Tonga and South Africa.
"Thierry Dusautoir will be our captain if he is 100 percent fit and the latest news about him is reassuring. From what we know, he has made a good recovery from his knee injury," said Saint-Andre.
"He will be at 100 percent for Toulouse in the European Cup and for his return to the French team."
Also returning to the squad after missing out on the first sessions in September are Toulouse No 8 Louis Picamoles and Castres prop Yannick Forestier.
They take over from Antonie Classen of Castres and the uncapped Antoine Burban of Stade Francais
Forestier is back in the French squad for the first time since the Six Nations game against Wales in February.
"He [Forestier] has made a good start to the season, moves well and we know how strong he is mentally, his character," Saint-Andre added.
The second training session at the team base in Marcoussis outside of Paris will run from October 27-30.
