Nikola Živković (Serbian Cyrillic: Никола Живковић; 1792–1870), known as Hadži-Neimar (Хаџи-Неимар), was the chief builder during the first reign of Serbian Prince Miloš Obrenović (1817–39).
Born in Voden (now Edessa, Greece) in 1792, he likely was schooled in Thessaloniki or Athens, where he had relatives.
His wife, Kostadinka Karkaljer, was from Magarevo (now North Macedonia).
A construction worker and contractor by trade, he became Obrenović's chief builder, entrusted with building all governmental- and royal buildings between 1820 and 1850.
The most notable buildings are Princess Ljubica's Residence and Residence of Prince Miloš.
