Natacha Bouchart demanded Emmanuel Macron does more to boost security in the northern French port city following the reported attack, according to Le Figaro.
The conservative mayor said: “The interior minister and the president must do more to reinforce security in Calais by sending more police to patrol the city’s streets.”
Mrs Bouchart’s comments came shortly after prosecutors announced the asylum seeker had admitted to the rape, which took place as the woman was heading home from work last Monday.
The mayor added: “There are currently some 450 police officers in Calais – they guard the entrance to the Eurotunnel and the entrance to the port, but at the moment they are doing nothing to protect locals.”
The attacker, from Eritrea, allegedly threatened his victim with a knife before dragging her into a wooded area and raping her.
He was identified by police the day after the attack with the aid of CCTV footage and is currently being held in pre-trial detention.
Mrs Bouchart said: “Migrants are acting with total impunity. They have all the rights, and yet no one knows their true identity – the people of Calais are fed up.”
She went on to call for the systematic fingerprinting of all irregular migrants in France.
The mayor said: “Calais locals have a lot of compassion for migrants, but they need to be told that they too have a moral obligation to respect the law.”
Mrs Bouchart added that the migrant crisis in Calais had already “gone past the point of no return.”
She said: “I have been trying to raise awareness of the scale of the crisis for years, but the government has repeatedly turned a deaf ear to my warnings. Locals are on edge. Everyone feared that something bad would happen, and it did. A line has been crossed.”
More than 600 UK-bound migrants have returned to the border town since the infamous ‘Jungle’ shanty town was razed to the ground by French authorities just over a year ago.
The government has since opposed charities’ plans to open a new emergency shelter in Calais, saying that it would act as a magnet and encourage migrants to return to the area.
