The present invention relates to a modified conjugated diene polymer, and more specifically, to a modified conjugated diene polymer in which a molecular weight distribution curve by gel permeation chromatography (GPC) has an unimodal shape, a molecular weight distribution (PDI; MWD) is less than 1.7, a Si content is 100 ppm or more based on weight, and 30 wt% or more of an aromatic vinyl monomer-derived repeating unit is included therein. The present invention also relates to a rubber composition which comprises the modified conjugated diene polymer.
