Sedad Hakkı Eldem, was a Turkish architect and one of the pioneers of nationalized modern architecture in Turkey.

Architecture of Turkey or Turkish architecture in the republican period is the architecture practised in Turkey since the foundation of the republic in 1923. In the first years of the republic, Turkish architecture was influenced by Seljuk and Ottoman architecture, in particular during the First National Architectural Movement. However, starting from the 1930s, architectural styles began to differ from traditional architecture, also as a result of an increasing number of foreign architects being invited to work in the country, mostly from Germany and Austria. The Second World War was a period of isolation, during which the Second National Architectural Movement emerged. Similar to Fascist architecture, the movement aimed to create a modern but nationalistic architecture.
