The present invention relates to a colorectal cancer diagnostic composition and method for detecting a diagnostic marker, more specifically to a colorectal cancer diagnostic composition comprising one or more mRNAs selected from the group consisting of lysyl-tRNA synthetase (KRS) and aminoacyl-tRNA synthetase complex-interacting multifunctional protein 1 (AIMP1) of a preparation for measuring protein expression levels thereof, and a method for detecting a marker form a sample obtained from a test subject in order to provide information necessary for diagnosing colorectal cancer. The colorectal cancer diagnostic marker comprising KRS and AIMP1, according to the present invention, has raised expression levels of same in the serum of a colorectal cancer patient in comparison to a normal control group. Therefore, whether colorectal cancer is present can be accurately and rapidly determined by measuring the expression levels of one or more markers selected from the group consisting of KRS and AIMP1.
