A variable valve mechanism control apparatus ensures intake negative pressure in an idling state, decelerating state, coasting state, and a decelerating and coasting state, to operate accessories or a brake device with the ensured intake negative pressure. In the variable valve mechanism control apparatus of an internal combustion engine including a variable valve mechanism which changes the phase of an operating angle of an engine valve, and a control device which changes the phase of the variable valve mechanism, when the temperature of the internal combustion engine is greater than a certain value which can be treated as a post-warm-up state, the accelerator opening is less than a certain value which can be treated as an idling state, and the intake negative pressure is less than a predetermined value, the phase is changed to converge to a predetermined phase at which a predetermined intake negative pressure occurs.
