All rights reserved..We present an update to the ultraviolet-to-radio database of global broadband photometry for the 79 nearby galaxies that comprise the union of the KINGFISH (Key Insights on Nearby Galaxies: A Far-Infrared Survey with $Herschel$) and SINGS ($Spitzer$ Infrared Nearby Galaxies Survey) samples. The 34-band data set presented here includes contributions from observational work carried out with a variety of facilities including $GALEX$, SDSS, Pan-STARRS1, $NOAO,\; 2MASS,$ $Wide-Field\; Infrared\; Survey\; Explorer,\; Spitzer,\; Herschel,\; Planck,\; JCMT$, and the $VLA$. Improvements of note include recalibrations of previously published SINGS BVR I and KINGFISH far-infrared/submillimeter photometry. Similar to previous results in the literature, an excess of submillimeter emission above model predictions is seen primarily for low-metallicity dwarf or irregular galaxies. This 33-band photometric data set for the combined KINGFISH+SINGS sample serves as an important multiwavelength reference for the variety of galaxies observed at low redshift. A thorough analysis of the observed spectral energy distributions is carried out in a companion paper.
