In an accessory mounting structure for an internal combustion engine, an accessory unit block detachably supporting an engine accessory is attached to the side of the body of the engine. The accessory unit block has an upper portion of a flat shape, and a lower portion extending away from the engine body to terminate in a water pump housing. An upper fixing boss is formed on an upper part of the upper portion, while a lower fixing boss is formed on an end, remote from the engine body, of an upper-side edge of the water pump housing. The engine accessory is fixedly mounted on the unit block by attaching fixing brackets to the upper and lower fixing bosses. The engine accessory is thus compactly accommodated.
