France plans to fix the legal age of sexual consent as 15, meaning sex with someone younger than that would be considered rape.
Equality Minister Marlène Schiappa welcomed the move, which follows advice from doctors and legal experts.
Currently, prosecutors must prove sex with someone under 15 was forced in order to bring rape charges.
The change comes amid uproar over two recent cases of men accused of having sex with 11-year-old girls.
Under the existing legislation, if there is no violence or coercion proved, offenders may only be charged with sexual abuse of a minor and not rape. This has a maximum sentence of five years in prison and a fine of €75,000 (£66,000; $87,000).
Sentences are the same for sexual assaults of minors and non-minors, but rape convictions carry much harsher punishments.
It had been discussing whether to set the age as 13 or 15, which is what groups fighting violence against children had campaigned for.
Ms Schiappa told AFP news agency that she was “very glad” that the higher age was chosen. The limit is also supported by President Emmanuel Macron.
