We have made IRAS (12, 25, and 60 micron) maximum entropy images of the
three known soft gamma repeaters SGR 0526-66, SGR 1806-20, and SGR 1900+14.
In addition we have obtained a high-resolution 10 micron image
of SGR 1900+14 using TIMMI at the ESO 3.6m telescope.
All three SGRs have associated with them an infrared source.
The infrared emission associated with SGR 0526-66 likely originates
from heated dust in the supernova remnant N49.
The infrared properties of the two galactic SGRs are similar; both are
unresolved at 12 and 25 microns, and extended at 60 microns.
The relation of these infrared sources (if any) to the SGRs is as yet unclear.
