We investigate a sample of 11 Galactic X‐ray sources recently discovered with  INTEGRAL  or  RXTE  with the goal of identifying their optical and/or near‐infrared (NIR) counterpart. For this purpose, new  Chandra  positions of nine objects are presented together with follow‐up observations of all the targets in the optical and NIR. For the four sources IGR J16194−2810, IGR J16479−4514, IGR J16500−3307 and IGR J19308+0530, the  Chandra  position confirms an existing association with an optical/NIR object, while for two sources, XTE J1716−389 and IGR J18490−0000, it rules out previously proposed counterparts indicating new ones. In the case of IGR J17597−220, a counterpart is selected out of the several possibilities proposed in the literature, and we present the first association with an optical/NIR source for IGR J16293−4603 and XTE J1743−363. Moreover, optical/NIR observations are reported for XTE J1710−281 and IGR J17254−3257; we investigate the counterpart to the X‐ray sources based on their  XMM–Newton  positions. We discuss the nature of each system considering its optical/NIR and X‐ray properties.
