The decree was approved at a cabinet meeting after a steady increase in cases over the last two months and should become effective from Thursday, a government source said.
Italian regions including Lazio, around the capital Rome, had already made face masks mandatory.
The decision came after the as new infections jumped to the highest daily tally since April. Data from the Health Ministry showed 3,678 cases were reported in the last 24 hours, up from 2,677 on Tuesday and surging past the 3,000 mark for the first time since April 24.
Italy is still recording far fewer daily cases than other large European countries such as France, Spain and Britain.
