An object of the present invention is to provide a novel method for producing a peptide utilizing a ligation reaction in which ligation efficiency is excellent and side reactions to other functional groups in the peptide are hard to occur, in comparison with the conventional native chemical ligation methods utilizing the thiol auxiliary group. The present invention provides a method for producing a peptide which comprises a step of causing a first peptide and a second peptide to react in the presence of a reducing agent to obtain a ligated product of the first peptide and the second peptide, wherein the first peptide contains, at the C-terminal end, an amino acid derivative having a thioester group, and the second peptide contains, at the N-terminal end, a serine or threonine derivative having a thiol auxiliary group.
