IRAS observations of the peculiar galaxy Arp 220 = IC 4553 show that it is extremely luminous in the far-infrared with a total luminosity of - 2 X 10^(12) L_☉. The infrared-to-blue luminosity ratio of this galaxy is - 80, which is the largest value of the ratio for galaxies in the UGC catalog, and places it in the range of the "unidentified" infrared sources recently reported by Houck et al. in the IRAS all-sky survey. Other observations of Arp 220, combined with the luminosity in the infrared, allow either a Seyfert-like or starburst origin for this luminosity.
