Don't Let Belgrade Drown

A green political organisation in Serbia.

A grassroots movement formed in 2014, aimed at criticising and reforming the current political system through "involving citizens in the development of their environment" and transparency. The organisation was made up of a group of people of different profiles, professions, and beliefs interested in urban and cultural policies, sustainable urban development, and equitable use of shared resources. In October 2022, NDB announced that together with local citizens' groups it would transform itself into a political party. It was succeeded by the Green–Left Front on 14 July 2023.

NDB was positioned on the left-wing on the political spectrum, and had adopted left-wing populist ideas,  and an anti-neoliberal, anti-nationalist, progressive, municipalist, and egalitarian ideology.  It maintained socialist and social-democratic economic policies, while it was also supportive of democratic socialism, and environmentalism. NDB described itself as a "green-left" organisation, while Radomir Lazović described NDB as a "transparent, democratic, solidarity[-based], green, and leftist movement". It was a member of the Progressive International.
