Precisionism (also known as Cubist Realism) is a style of representation in which an object is rendered realistically, but with an emphasis on its geometrical form. An important development in American Modernism, it was inspired by the development of Cubism in Europe.

Charles Sheeler, Charles Demuth and Georgia O"Keeffe, as the most typical representatives, were inspired by the development of Cubism in Europe. Architecture, in particular the architecture of industrial buildings was their favorite subject. In their pictures people and nature were usually absent. The visual language that Precisionists developed combined realism and geometric schematization. Demuth regarded his paintings as abstractions produced from observed reality. Some art historians have used the term "cubo-realism" to describe his work.

Precisionism was an important development in American Modernism and in some respects, Precisionists works are harbingers of the Pop Art aesthetic. Dealing as it did with pure form more than with narrative or subject matter, Precisionism gradually evolved towards Abstraction, and faded away as an important influence.
