The first subarcsecond resolution mid-IR images of the nuclei of two galaxies from the IRAS bright sample, NGC 1614 and NGC 7469, are described. The starburst galaxy NGC 1614 contains a double structure in the nuclear region. Most of the flux, 78 percent of 650 +/- 50 mJy, is emitted in two unresolved regions of 0.6 arcsec FWHM (190 pc at 64 Mpc) of nearly equal strength separated by 0.6 arcsec (200 pc). Most of the remaining flux is derived from a small arm 1 arcsec in length (310 pc). The Seyfert I galaxy NGC 7469 shows an elongated structure, 1.4 x 0.7 arcsec (450 x 220 pc at 66 Mpc).
