QSO J2233-606 was observed with the Space Telescope Imaging Spectrograph during the HDF-South campaign. The spectroscopic observations covered wavelengths from 1150 to 3560 {Å} at a range of resolutions. The QSO spectrum is attenuated by a Lyman-limit absorption line system at z ~1.9, but the flux recovers in the far-UV. Most of the spectroscopic observing time (155 ks) was devoted to obtaining observations with the medium-resolution echelle grating at a resolution of 10 km/s. The spectra show a rich forest of absorption lines, some arising from Lyman \alpha in the redshift range 1.2 to 1.5, and others from higher order Lyman series lines of higher-redshift systems. At shorter wavelengths, some strong absorption line systems are seen at the 250-400 km/s resolution with the low-resolution gratings. The higher-redshift Lyman alpha forest is detected at 50 km/s resolution in the 3100-3560 {Å} region.
