The National Coordination Committee for Democratic Change (NCC), or National Coordination Body for Democratic Change (NCB) (Arabic: هيئة التنسيق الوطنية لقوى التغيير الديمقراطي), is a Syrian coalition of opposition movements formed at the onset of the Syrian civil war. Chaired by Hassan Abdel Azim, it consists of 13 left-wing political parties and "independent political and youth activists". It has been defined by Reuters as the internal opposition's main umbrella group. The NCC initially had several Kurdish political parties as members, but all except for the Democratic Union Party left in October 2011 to join the Kurdish National Council.

At the beginning of the civil war, relations with other Syrian opposition groups were generally poor. The Syrian Revolution General Commission, the Local Coordination Committees of Syria or the Supreme Council of the Syrian Revolution were critical of the NCC's calls to dialogue with the Syrian government. In September 2012, the Syrian National Council (SNC) reaffirmed that despite broadening its membership, it would not join with "currents close to [the] NCC". Despite recognizing the Free Syrian Army on 23 September 2012, the FSA has dismissed the NCC as an extension of the government, stating that "this opposition is just the other face of the same coin". Some opposition activists have accused the NCC of being a front organization for Bashar al-Assad's government and some of its members of being ex-government insiders.

The NCC differed from the SNC on two main points of strategy:

Eventually, the NCC cooperated with the Syrian National Coalition as part of the Syrian peace efforts.

The Coordination Committee is largely based inside Syria, and was formed in 2011 at a congress in Damascus. It gathers all of the political parties of the National Democratic Rally, formerly Syria's main secular opposition coalition, and few other organizations. It has a generally secular membership, although not exclusively so. Most member organizations have a leftist profile, while some are also strongly Arab nationalist or Kurdish nationalist. Damascus-based lawyer Hassan Abdul Azim, the chairman, is also the spokesperson of the National Democratic Rally and the chairman of the Democratic Arab Socialist Union, a banned Nasserist opposition party. The Coordination Committee's spokesperson abroad is Haytham Manna, a Paris-based author and human rights activist, who spent three decades as a human rights activist and spokesperson for the Arab Commission for Human Rights (ACHR), which he helped create.

At an 18 March 2012 demonstration during the Syrian civil war, a protest organised by the NCC in Damascus was smaller than countryside demonstrations. The demonstration had been announced publicly beforehand. Participants chanted, "The people want the fall of the regime". Several were beaten by security forces, and eleven members of the NCC were briefly detained.

The NCC has been hosted by Russia for talks with the Syrian government. During these talks in April 2012 SANA, the official news agency, claimed that the NCC and the government were in widespread agreement.

In September 2012 the NCC met with Chinese Foreign Minister Yang Jiechi, and called for a four-point plan which included political transition. Upon returning to Syria via Damascus International Airport, two of the NCC members who had been at the meeting in China along with another NCC member who had come to collect them were detained by the Syrian government, with all contact being lost with them since 5:30 on 20 September. The NCC spokesman Khalaf Dahowd described this detainment as kidnapping, with the NCC executive further elaborating that they believed the three members to have been "forcibly disappeared" by the Syrian Air Force Intelligence Directorate. The Syrian government on the other hand claimed that the NCC members were captured by "terrorist groups", despite having detained five other NCC members for the first time on Monday that week.
