The present invention relates to a process for preparing a prostaglandin derivative and an intermediate therefor. In accordance with the present invention, the prostaglandin F (PGF) derivative can be efficiently prepared with high purity by removing the protecting group of a protected prostaglandin E (PGE) derivative obtained from conjugate addition and then stereoselectively reducing the ketone group on the cyclopentanone ring of the PGE derivative.
