Abstract
Four Soft Gamma Repeaters (SGRs) have now been identified with certainty, and a fifth has possibly been detected. I will review their X-ray and gamma-ray properties in both outburst and quiescence. The magnetar model accounts fairly well for the observations of SGR1806−20 and SGR1900+14 , but data are still lacking for SGR1627−41 and SGR0525−66 . The locations of the SGRs with respect to their supernova remnants suggest that they are high-velocity objects.
