Observations of the radio source 4C74.26 with the Cambridge Low-Frequency Synthesis Telescope have shown it to be a 10-arcmin double. It is identified with a quasar with a redshift of 0.104, measured with the University of Hawaii 88-inch telescope, giving the source a projected linear size of 1.6 Mpc and making it the largest-known radio source associated with a quasar. The optical spectrum and image, radio maps and JCMT millimeter observations are presented here. The radio properties of 4C74.26 are remarkably similar to those of other giant sources identified with galaxies - despite its very much larger non-stellar optical nuclear luminosity - as well as to those of 4C34.47, the only other giant source associated with a quasar.
