A computer-on-module (COM) is a type of single-board computer (SBC), a subtype of an embedded computer system. The COM module is a complete computer built on a single circuit board. The design is centered on a single microprocessor with RAM, input/output controllers and all other features needed to be a functional computer on the one board. However, unlike a single-board computer, the COM module will usually lack the standard connectors for any input/output peripherals to be attached directly to the board. Instead, the wiring for these peripherals are bussed out to pin-headers on the board.

The module will usually need to be mounted on a baseboard which breaks the bus out to standard peripheral connectors.

The terms "Computer-on-Module" and "COM" were coined by Venture Development Corporation (Natick, MA, USA) to describe this class of embedded computer boards.

The term became more notable upon industry standardization of the COM Express format.
