France will ban smoking on beaches and in parks, public gardens and bus shelters from Sunday, the government said.
The decree, published in the official government gazette Saturday, will also ban smoking outside libraries, swimming pools and schools, and is aimed at protecting children from passive smoking.
Health and family minister Catherine Vautrin said in May that tobacco must disappear where there are children.
The freedom to smoke "stops where children's right to breathe clean air starts", she said.
Offenders face a fine of up to €135 ($154), Vautrin added.
The ban will not extend to France's iconic cafe terraces however, the minister said.
Electronic cigarettes, which have boomed in France in recent years, are also not covered.
An estimated 35 percent of France's population are smokers – higher than the averages for Europe (25 percent) and the world (21 percent), according to the World Health Organization.
Around 75,000 people are estimated to die from tobacco-related complications each year in France.
