Brutalist architecture is an architectural style that emerged during the 1950s in the United Kingdom, among the reconstruction projects of the post-war era. Brutalist buildings are characterised by minimalist constructions that showcase the bare building materials and structural elements over decorative design. The style commonly makes use of exposed, unpainted concrete or brick, angular geometric shapes and a predominantly monochrome colour palette; other materials, such as steel, timber, and glass, are also featured.

粗獷主義（英語：Brutalism，又稱蠻橫主義或粗野主義）是建築流派的一種，可歸入現代主義建築流派當中。主要流行的時間介於1953年到1967年之間，由功能主義發展而來。

其建築特色，是從不修邊幅的鋼筋混凝土（或其它材料）的毛糙、沉重、粗野感中尋求形式上的出路。
