A variable valve control apparatus includes a variable valve timing mechanism that adjusts an actuation timing of an intake valve and an actuation timing of an exhaust valve; a variable working angle mechanism that adjusts a working angle of the intake valve; a variable valve control section that controls at least one of the variable valve timing mechanism and the variable working angle mechanism based on an engine load; and a negative pressure suppression control section. The negative pressure suppression control section suppresses a negative pressure of an inside of a cylinder when the negative pressure suppression control section determines that both of the intake valve and the exhaust valve close after an intake top dead center, based on opening conditions of the intake valve and the exhaust valve.
