We present recent results of a search for pulsed very-high-energy (VHE) gamma-ray emission from pulsars using data taken with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging Cherenkov telescopes located in Namibia. The data set, accumulated during four years of operation until 2006, comprises observations of eleven young pulsars, selected according to their spin-down luminosity relative to distance, and two millisecond pulsars. No evidence for pulsed emission was found in any data set and differential upper limits on pulsed energy flux were derived, and compared to a variety of model predictions on VHE gamma-ray emission from the vicinity of pulsar magnetospheres.
