Fast Radio Bursts (FRBs) are highly energetic, extremely short-lived bursts of radio flashes.Despite extensive research, the exact cause of these outbursts remains a mystery. One of themost accredited models suggests that they originate from highly magnetized and rapidly spinningneutron stars known as magnetars. The high luminosity, short duration, and high dispersionmeasure of these events suggest they result from extreme, high-energy astrophysical processesof extragalactic origin. The number of detected FRBs, including repeating ones, has grownrapidly in recent years. Except for FRB20200428, that is associated to the galactic magnetarSGR1925+2154, no multi-wavelength counterparts to any FRB has been detected yet. The HighEnergy Stereoscopic System (H.E.S.S.) telescope has developed a program to uncover the natureof these mysterious events by searching for their gamma-ray counterparts. This contributionprovides an overview of the searches for FRB sources conducted by H.E.S.S., including follow-upobservations and simultaneous multi-wavelength campaigns with radio and X-ray observatories
