We report the discovery of about thirteen new infrared diffuse interstellar bands (DIBs) in the H-band spectra of stars in the Galactic center. Their identification as DIBs is supported by the presence of the stronger H-band DIBS in spectra toward stars in the Cygnus OB2 association. The H-band DIBs, which add to the over 500 DIBs previously known, are the longest wavelength ones reported to date and the first found on Galactic center sightlines.
