IGR J19140+0951 was discovered by INTEGRAL in 2003 in the 4-100 keV band .
Observations with INTEGRAL and RXTE provide a tentative identification as a high-mass X-ray binary ( HMXB ) with a neutron star as accretor .
However , an optical counterpart was thus far not established , nor was the presence of a pulsar which is commonly observed in HMXBs .
We observed IGR J19140+0951 with Chandra and find the source to be active at a similar flux as previous measurements .
The lightcurve shows a marginally significant oscillation at 6.5 ks which requires confirmation .
We determine a sub-arcsecond position from the Chandra data and identify the heavily reddened optical counterpart 2MASS 19140422+0952577 in the 2MASS catalog .
Optical follow-up observations with the William Herschel Telescope at La Palma exhibit a continuum spectrum coming out of extinction above 7000 Å without strong absorption or emission features . V,I and K _ { s } band photometry point to an optical counterpart extincted by A _ { V } = 11 \pm 2 .
The extinction is consistent with the interstellar value .
None of the data reject the suspicion that IGR J19140+0951 is an HMXB with additional circumstellar obscuration around the accretor .
