The present invention relates to a modified conjugated diene-based polymer, and more particularly, to a modified conjugated diene-based polymer having a unimodal shape of gel permeation chromatography (GPC) molecular weight distribution curve, a molecular weight distribution (PDI; MWD) of less than 1.7, and a Si content of 100 ppm or more based on weight, and including a repeating unit derived from an aromatic vinyl monomer in an amount of greater than 0 wt% and less than 15 wt%, and a rubber composition including the same. |
