An engine block is the structure which contains the cylinders, and other parts, of an internal combustion engine. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries.

The term "cylinder block" is often used interchangeably with engine block, although technically the block of a modern engine (i.e. multiple cylinders in a single component) would be classified as a monobloc. Another common term for an engine block is simply "block".

The main structure of an engine (i.e. the long block, excluding any moving parts) typically consists of the cylinders, coolant passages, oil galleries, crankcase and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each of these elements, which were bolted together during engine assembly. Modern engines, however, often combine many of these elements into a single component, in order to reduce production costs.
