According to the invention, an EGR control apparatus of an engine includes intake ports to which an intake passage is connected, the intake ports opening into each combustion chamber of the engine, an EGR port to which an EGR passage branching out from an exhaust passage is connected, the EGR port opening into each combustion chamber of the engine, an electrically-operated compressor disposed in the EGR passage for regulating pressure at which EGR gas is introduced into each combustion chamber, and an EGR control valve disposed in the EGR passage at a point downstream of the electrically-operated compressor for controlling the amount of EGR gas introduced into each combustion chamber. The EGR passage branches out from the exhaust passage at a point downstream of an emission control device disposed in the exhaust passage.
