康斯坦丁·布朗库西（罗马尼亚语：Constantin Brâncuşi 罗马尼亚语发音：[konstanˈtin brɨnˈkuʃʲ]，1876年2月19日－1957年3月16日），罗马尼亚、法国雕塑家和现代摄影家。他是继奥古斯特·罗丹之后，20世纪最具影响力的雕塑家，被誉为现代主义雕塑先驱。他在1904年进入布加勒斯特国立艺术大学就读，毕业后前往巴黎发展。在完成传统学院训练后，布朗库西受到非洲艺术和罗马尼亚民间艺术薰陶，逐渐形塑出他独特的雕塑风格。

布朗库西的雕塑作品常选用铜、大理石、木材和石膏素材，刻划卵形及飞鸟等抽象的主题，引领视觉艺术领域的前卫思潮。他在1910年接触立体主义并受其影响，开始尝试以有限的题材，透过不同材质的运用进行创作。1938年，布朗库西在特尔古日乌完成战争纪念碑创作，完整融合建筑与雕塑艺术，成就艺术史上的一项里程碑。

Constantin Brâncuși (Romanian: [konstanˈtin brɨŋˈkuʃʲ]; February 19, 1876 – March 16, 1957) was a Romanian sculptor, painter and photographer who made his career in France. Considered a pioneer of modernism, one of the most influential sculptors of the 20th-century, Brâncuși is called the patriarch of modern sculpture. As a child he displayed an aptitude for carving wooden farm tools. Formal studies took him first to Bucharest, then to Munich, then to the École des Beaux-Arts in Paris from 1905 to 1907. His art emphasizes clean geometrical lines that balance forms inherent in his materials with the symbolic allusions of representational art. Brâncuși sought inspiration in non-European cultures as a source of primitive exoticism, as did Paul Gauguin, Pablo Picasso, André Derain and others. But other influences emerge from Romanian folk art traceable through Byzantine and Dionysian traditions.
