A joint statement said they condemned the violence, attacks on police and threats to politicians which have been issued in recent weeks.
The almost eight-hour meeting was then adjourned to reconvene in the New Year.
A statement said: "Leaders welcomed the opportunity to meet and engage in a discussion of the events over recent days and weeks.
"Party leaders reaffirmed their commitment to the rule of law and the primacy of the political process and deplored violence, attacks on the PSNI, as well as threats to elected representatives.
"Recognising the importance of culture and identity within the community, and conscious of the impact on business, political leaders re-emphasised that their task was to find political solutions and to ensure peace and stability for the people of Northern Ireland."
There has been unrest across NI over the past three weeks following Belfast City Council's decision to reduce the number of days the Union flag flies at City Hall.
More than 40 police officers have been injured dealing with bouts of violence and 42 people have been arrested and charged.
Several politicians have received death threats and business in Belfast has been disrupted in the busy run-up to Christmas.
The leaders continued: "The meeting was adjourned and will reconvene in the New Year to further discuss these matters."
