Postconstructivism was a transitional architectural style that existed in the Soviet Union in the 1930s, typical of early Stalinist architecture before World War II. The term postconstructivism was coined by Selim Khan-Magomedov, a historian of architecture, to describe the product of avant-garde artists' migration to Stalinist neoclassicism. Khan-Magomedov identified postconstructivism with 1932–1936, but the long construction time and vast size of the country extended the period to 1941.

Existence of this style is evident, but Khan-Magomedov's explanation of its evolution as a natural process inside the architectural community, rather than as a result of political direction by the Party and State, is strongly disputed.

This section is based on Khan-Magomedov's Soviet avant-garde architecture, vol.1, "Avant-garde to postconstructivism and beyond"

In 1932–1933, during the Palace of Soviets contest, the State sent a clear message to architects that the age of experiment was over and the new buildings must follow the classical canon. At this time, the architectural profession was divided into three generations:

According to Khan-Magomedov, two forerunners of the style were Ivan Fomin and Ilya Golosov. They converged on the same form from opposite directions – neoclassicism and constructivism. Fomin's concept, easily formulated, erected in steel and granite in Moscow (Dynamo Building), was well understood even by the inexperienced youth. "The youth instinctively followed those who managed to declare their stance clearly. The youth believed that this period is a self-sufficient cultural stage, not a transition to something else". In 1933–34, Golosov publicly disposed of the avant-garde. He returned to Neoclassicism, trying to avoid direct citations from the past. For example, he used square columns instead of traditional, round ones. Square, lean columns without capitals became a trademark feature of the emerging style. Golosov's entries in public design contests exposed his style to numerous followers.

Khan-Magomedov defined postconstructivism as "neoclassical shapes without neoclassical detailing". Golosov and his followers deliberately replaced the proven historical details (columns, capitals, friezes, and cornices) with their inventions – to differentiate themselves from pure Revivalists. The main volumes follow the classical rules and usually are perfectly symmetrical.
