Demonstrators gathered near the French military base in the capital Niamey, some waving Nigerien or Russian flags, others with placards calling for the departure of French troops.
Former colonial power France still has 1,500 soldiers based in Niger. They had been helping the deposed President Mohamed Bazoum in the fight against jihadist forces active there, before military officers toppled him in the July 26 coup.
The National Council for the Safeguard of the Homeland (CNSP) led by General Abdourahamane Tiani has detained him and his at the presidential palace.
Sunday's rally started at dawn on a roundabout near Niamey airport by the Nigerien air base where the French force is located, as demonstrators answered an appeal from organisations backing the country's new rulers.
"We don't want the French army in Niger," said one demonstrator, Abou Kountche. "Let the French leave."
"The French say that Niger is a poor country, but when we tell them to go home, they refuse," said restaurateur Adama Assane.
On Friday, Niger's foreign ministry announced that French ambassador Sylvain Itte had 48 hours to leave, saying he had refused to meet with the new rulers and citing French government actions that were "contrary to the interests of Niger".
Paris has rejected the demand and said the "putschists do not have the authority to make this request", insisting that the government of Bazoum that they had overthrown remained the legitimate authority.
On Saturday some 20,000 people rallied in the Senyi Kountche stadium to support the country's new military rulers and call for the removal of French soldiers.
