Some migrants were injured by the blaze which ignited just hours after the French capital was plunged into terror.
One aid worker said: "The details are sketchy at the moment. What we do know is that a number of people in the camps have been injured and we are trying to find medical care for them."
He added: "The refugees are currently being taken to the Ashram centre and women’s shelters while the fires are being put out."
It comes just days after a French politician branded the camp a "lawless slum" where violence is escalating to the point of "guerrilla warfare".
It comes as at least 140 people are reported to have been killed and dozens more injured during a series of attacks across Paris.
The two attackers were killed in a police operation to rescue the hostages at the Bataclan theatre, according to French media.
