During a program of mapping a complete sample of extended radio sources with the Molonglo Observatory Synthesis Telescope (MOST), the source MSH 05-22 (0503-286) was discovered to be a giant radio source. Our map at 843 MHz clearly suggests the association of the observed radio emission, extending over 42 arcmin, with a 15.5 mag D-galaxy. The galaxy redshift of z = 0.0384 leads to a projected linear extent of 2.6 Mpc (H0 = 50 kms-1Mpc-1), making this the largest known radio source in the southern sky.
