We report on the detection of a soft spatially extended component of X‐ray emission around four intermediate‐redshift 3C quasars observed with Chandra : 3C 254, 3C 263, 3C 275.1 and 3C 281. The bolometric luminosity of this emission ranges over 0.3–1.6 × 10 44 erg s −1 , and extends to length‐scales of over 350 kpc at the redshift of the quasar. The X‐rays are most likely thermal emission from the intracluster medium of a cluster of galaxies around each quasar, which provides the working surface for the powerful radio lobes. Some X‐ray emission is also seen to be associated with the radio plasma.
