Niall Ó Donnghaile said he made the changes to create a more "balanced" setting that is welcoming to all citizens and represents the entire city.
The mayor said the space previously only had items representing one of the city's traditions - unionism - on display.
"When I entered two weeks ago there were four portraits of various members of the British royal family up around nine spaces in the parlour," he told UTV.
"Obviously that was quite unrepresentative and unbalanced in regards to the makeup of the city so I have begun a process to make this place a bit more reflective of Belfast as a whole."
Mr Ó Donnghaile, who was appointed the city's youngest ever mayor last month, says he aims to create a civic space that all people can feel at ease in.
He has kept pictures of the Queen and Prince Philip on display, and added that there is also room for a piece that represents the city's new ethnic communities.
"From the beginning I've made it clear I wanted to be a mayor for all of the citizens," he says.
"That's why I recognise there are people with an affinity to the royal family, so I kept the Queen and her husband in the parlour."
The move has been criticised by DUP councillors, who have called on Mr Ó Donnghaile to return the pictures to their original positions.
Christopher Stalford, the party's deputy group leader on Belfast City Council, said removing the portraits will "cause hurt" in the community.
"Her Majesty, The Queen Mother was a much loved public figure on all sides of the community and the Prince of Wales has engaged in marvellous work helping young people through the Prince's Trust," Mr Stalford said.
"The exclusion of their portraits will cause hurt in the community and the Lord Mayor needs to reflect on that.
"I would urge the Lord Mayor to show positive leadership and reverse his decision. You cannot reach out across boundaries whilst practising acts of exclusion like this."
