The High Energy Stereoscopic System (H.E.S.S.) consists of four ImagingAtmospheric Cherenkov Telescopes (IACTs) in Namibia for the detection of cosmicvery-high-energy (VHE) gamma-rays. Gamma-ray bursts (GRBs) are among thepotential VHE gamma-ray sources. VHE gamma-emission from GRBs is predicted bymany GRB models. Because of its generally fast-fading nature in many wavebands,the time evolution of any VHE gamma-radiation is still unknown. In order toprobe the largely unexplored VHE gamma-ray spectra of GRBs, a GRB observingprogram has been set up by the H.E.S.S. collaboration. With the highsensitivity of the H.E.S.S. array, VHE gamma-ray flux levels predicted by GRBmodels are well within reach. We report the H.E.S.S. observations of andresults from some of the reported GRB positions during March 2003 - May 2006.
