Emilijan Josimović (Moldova Nouă, Caraș-Severin County, then part of Austrian Empire, 1823 – Sokobanja, 25 May 1897) was a Serbian urban planner who designed the first urban plan of Belgrade at the same time as Cerdà in Barcelona and Georges-Eugène Haussmann in Paris from 1853 until 1870. Josimović was arguably the first modern Serbian urbanist and the first modern professor of architecture in Serbia.
