In this paper we describe the High Pressure Gas Scintillation Proportion Counter, one of the Narrow Field Instrument of the X-ray astronomy satellite BeppoSAX. Sensitive in the 4-120 keV band, the HPGSPC will study all astrophysical sources emitting in the poorly studied hard X-ray band. The design and performances of the instrument are reported together with results of the on-ground calibration data analysis.
