Large numbers reportedly turned out in Rasht, in the north, and Kermanshah, in the west, with smaller protests in Isfahan, Hamadan and elsewhere.
The protests began against rising prices but have spiralled into a general outcry against clerical rule and government policies.
A small number of people have been arrested in Tehran, the capital.
They were among a group of 50 people who gathered in a city square, Tehran’s deputy governor-general for security affairs told the Iranian Labour News Agency.
The governor-general of Tehran earlier said that any such gatherings would be firmly dealt with by the police, who are out in force on main intersections.
