Demonstrations were held in the capital Warsaw, the northern city of Gdańsk and central Łódź, among others.
In Warsaw, hundreds of protesters gathered in front of the headquarters of the ruling conservative party Law and Justice (PiS), and later marched to the Constitutional Tribunal building.
They brandished signs saying “Fight with the virus, not women!” and “Keep your hands off my daughter!”.
The demonstrations were sparked by a ruling from Poland's Constitutional Tribunal on Thursday which heralded a tightening of the country's abortion laws, already among the toughest in the European Union.
Further protests are planned for Monday and Wednesday.
