In this talk I will present some results obtained on the study of OB stars using the APOGEE spectrographs. We developed a near-infrared semi-empirical spectral classification method that was successfully used in the discovery and classification of several new OB stars in the Galaxy. Our results confirm that the APOGEE spectrographs can be used as a powerful tool in surveys aiming to unveil and study large number of moderately and highly obscured OB stars still hidden in the Galaxy.
