Seventy protestors gathered outside the City Hall at lunchtime on Saturday.
Police attended the scene on Northern Ireland’s busiest shopping day - the last Saturday before Christmas.
Around 20 of the protestors then moved their demonstration to the Upper Newtownards Road. Both protests passed off peacefully and by 4pm police said all protestors had dispersed.
On Friday evening protests took place across Northern Ireland as loyalists continued to cause disruption in a bid to have the flag reinstated at city hall all year round.
While most were peaceful two petrol bombs were thrown at police on the Lower Newtownards Road.
The Police Service of Northern Ireland dealt with more than 50 protests within an hour across the region as commuters were heading home from work.
Officers encountered some minor incidents in the Lower Newtownards Road area where petrol bombs were thrown at them. There were no injuries.
A PSNI spokeswoman said: “Most of the protests were peaceful.”
Demonstrations have been continuing since the start of the month against Belfast City Council’s decision to reduce the number of days the flag is flown from the city hall.
