An object of the present invention is to provide a method of industrially producing a high-purity L-cyclic amino acid more inexpensively and with a high efficiency, from a cyclic amino acid having a double bond at the 1-position. The present invention provides a method in which an L-cyclic amino acid is produced by allowing a cyclic amino acid having a double bond at the 1-position to react with a specific enzyme having a catalytic ability to reduce a cyclic amino acid having a double bond at the 1-position to produce an L-cyclic amino acid.
