We present the results of our optical identification of the hard X-ray source IGR J18257–0707
through its spectrophotometric observations with the optical RTT-150 telescope. The accurate position
of the X-ray source determined using Chandra observations has allowed this source to be confidently
associated with a faint optical object (m R ≈ 20.4) whose optical spectrum exhibits a broad Hα emission line
at redshift z = 0.037. Thus, the source IGR J18257–0707 is a type-1 Seyfert galaxy at redshift z = 0.037.
