Optical identifications are presented for 66 IRAS point sources in the region of the Fornax cluster of galaxies, 106 IRAS point sources in the region of the Hydra I cluster of galaxies (Abell 1060), and 59 IRAS point sources in the region of the Coma cluster of galaxies (Abell 1656). Eight other sources in Hydra I do not have optical counterparts and are very probably due to IR cirrus. Twenty-three (35 percent) of the Fornax sources are associated with stars and 43 (65 percent) with galaxies; 48 (42 percent) of the Hydra I sources are associated with stars and 58 (51 percent) with galaxies; 18 (31 percent) of the Coma sources are associated with stars and 41 (69 percent) with galaxies. The stellar and infrared cirrus surface density is consistent with the galactic latitude of each field.
