<P>PROBLEM TO BE SOLVED: To provide an EGR control device reducing occurrence of knocking due to reduction in an EGR gas flow rate. Ž<P>SOLUTION: The exhaust gas recirculation control device includes: an EGR device 40 recirculating a part of exhaust gas from an exhaust pipe 31 to an intake pipe 21 through an EGR pipe 41; and a control device 50 controlling an EGR gas amount as a flow rate of exhaust gas recirculated according to opening of an EGR valve 42 installed in the EGR pipe 41. During reduction of a flow rate when the EGR gas amount is lowered, the flow rate of the EGR gas is regulated by performing increasing correction of the opening of the EGR valve 42.
