The present invention relates to a method of preparing a modified conjugated diene-based polymer, and more particularly, to a method of preparing a modified conjugated diene-based polymer, including: (S1) preparing an active polymer with an organic metal bonded thereto by polymerizing a conjugated diene-based monomer in a hydrocarbon solvent in the presence of an organometallic compound; and (S2) mixing the active polymer prepared according to process S1 with a modifier, wherein the mixing of process S2 is performed at a Reynolds number of 20 or less for 1 minute or more, the Reynolds number being maintained within a range of ±5 of a Reynolds number when the modifier is added (wherein the range is between greater than 0 to 20 or less).
