Provided is a conjugated diene-based copolymer composition, and more particularly, a conjugated diene-based copolymer composition including: a first conjugated diene-based copolymer including 20 wt% to 60 wt% of an aromatic vinyl monomer-derived repeating unit, 35 wt% to 75 wt% of a first conjugated diene-based monomer-derived repeating unit, and 1 wt% to 10 wt% of a hydroxyalkyl (meth)acrylate monomer-derived repeating unit, and having a Mooney viscosity (MV) at 100 °C of 30 to 120; and a second conjugated diene-based copolymer including 20 wt% to 60 wt% of an α-methylstyrene monomer-derived repeating unit and 40 wt% to 80 wt% of a second conjugated diene-based monomer-derived repeating unit, and having a Mooney viscosity (MV) at 100 °C of more than 120 and equal to or less than 200.
