Zusammenfassung:	A conjugated diene-based copolymer composition, a method of preparing the same, and a rubber composition including the same are provided. The conjugated diene-based copolymer composition includes a first conjugated diene-based copolymer and a second conjugated diene-based copolymer each including a repeating unit derived from an aromatic vinyl monomer, a repeating unit derived from a conjugated diene-based monomer, and a repeating unit derived from a hydroxyalkyl (meth)acrylate monomer. The first conjugated diene-based copolymer includes 0.01 wt% to 1 wt% of the repeating unit derived from the hydroxyalkyl (meth)acrylate monomer, and the second conjugated diene-based copolymer includes 4.5 wt% to 6.5 wt% of the repeating unit derived from the hydroxyalkyl (meth)acrylate monomer.
