The present invention relates to a method for producing a modified conjugated diene polymer, and more particularly, an activity in which an organic metal is bonded by polymerizing a conjugated diene monomer in a hydrocarbon solvent in the presence of an organic metal compound. A step (S1) of producing a polymer, and a step (S2) of reacting or coupling the active polymer produced in the step (S1) with a modifier, wherein the step (S1) comprises 2 The present invention provides a method for producing a modified conjugated diene polymer, which is continuously carried out in a polymerization reactor of at least a group, and the polymerization conversion rate in a first reactor of the polymerization reactors is 50% or less.
