OH absorption against PSR B1718-35 at (l,b)=351.688°, +0.671° has been discovered at 1665 and 1667 MHz using the Green Bank Telescope. The absorption appears to arise at the interface of an H II region and a molecular cloud that are likely associated with the high-mass star-forming region NGC 6334. Beam dilution is found to be the cause of differences between the opacity of the OH against the Galactic background continuum emission and against the pulsar. The OH cloud is approximately 3x1.3 pc and is located behind the H II region.
