Using the AdS/CFT correspondence, the effect of alpha'-correction on the value of Chiral Magnetic Effect (CME) is computed by adding a number of spinning probe D7-branes in the alpha'-corrected background. We numerically show that the magnitude of CME rises in the presence of alpha'-correction for massive solutions and this increase is more sensible at higher temperatures. However, this value does not change for massless solution. Although some of the D7-brane embeddings have no CME, after applying the alpha'-correction they find a non-zero value for the CME. We also show that the effect of alpha'-correction removes the singularity from some of the D7-brane embeddings.
