In order to look for the quiescent longer-wavelength counterpart of the hard X-ray transient source IGR J17177-3656 (ATels #3223, #3226, #3236), we searched the archival frames of the near-infrared (NIR) VVV survey (vvvsurvey.org; Minniti et al. 2010, New Astron., 15, 433) of the Galactic Bulge and inner arms, which is being obtained with the 4.1m VISTA telescope at Cerro Paranal (Chile). JHKs images were acquired on 23 April 2010 between 07:43 and 07:51 UT under an average seeing of 0.66 arcsec; a further Ks image was secured on 15 October 2010 at 00:43 UT with a seeing of 0.78 arcsec.
