We present Spitzer IRAC 3.6–8 μ m and Multiband Imaging Photometer 24 μ m point-source catalogs for M31 and 15 other mostly large, star-forming galaxies at distances ∼3.5–14 Mpc, including M51, M83, M101, and NGC 6946. These catalogs contain ∼1 million sources including ∼859,000 in M31 and ∼116,000 in the other galaxies. They were created following the procedures described in Khan et al. through a combination of point-spread function (PSF) fitting and aperture photometry. These data products constitute a resource to improve our understanding of the IR-bright (3.6–24 μ m) point-source populations in crowded extragalactic stellar fields and to plan observations with the James Webb Space Telescope .
