A senior health official announced today that a woman whose partner travelled to Brazil, the epicentre of the virus outbreak, was affected.
Earlier this week, U.S. officials said they were investigating 14 reports of the mosquito-borne disease that may have been transmitted through sex - including to several pregnant women.
Francois Bourdillon, head of France's Institute for Public Health Surveillance, said the infected woman was the country's "first confirmed indigenous case of transmission".
"This was a woman who had never travelled. Her partner had come from Brazil, so she was tested," Mr Bourdillon said, adding that both patients were doing well.
There is no cure or treatment for the virus which has so far spread to more than 30 countries.
