This article discusses the imaging of 3D objects. For an abstract mathematical discussion, see Projection (linear algebra).

Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional images of three-dimensional objects. The objects are not in perspective, so they do not correspond to any view of an object that can be obtained in practice, but the technique does yield somewhat convincing and useful images.

Oblique projection is commonly used in technical drawing. The cavalier projection was used by French military artists in the 18th century to depict fortifications. Oblique projection was used almost universally by Chinese artists from the first or second centuries to the 18th century, especially when depicting rectilinear objects such as houses.<ref name=Cucker299>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>
