<em>Version 1 of the void catalogs. The peer-reviewed publication for these catalogs will be submitted to the Astrophysical Journal Supplemental Series, an American Astronomical Society journal. Please cite this article when using any of these catalogs.</em> We provide three void catalogs using a volume-limited subsample of the SDSS DR7 using new implementations of two different void-finding algorithms from the Void Analysis Software Toolkit (VAST): VoidFinder and Voronoi Voids (V<sup>2</sup>). We identify 1159 cosmic voids with VoidFinder, 534 with V<sup>2</sup> using VIDE pruning, and 518 with V<sup>2</sup> using REVOLVER pruning. These catalogs exist within the SDSS DR7 main survey volume, out to a maximum redshift of 0.114. Effective radii and centers for all voids are computed and included with the catalogs; the median void effective radius is 15-17 <em>h</em><sup>-1</sup> Mpc for all three catalogs, and none have an effective radius larger than 54 <em>h</em><sup>-1</sup> Mpc. All catalog files are in ASCII format with commented headers. An example of each file (except the galaxy file associated with V<sup>2</sup>) is shown in Tables 1-5 in the associated journal article. For each galaxy in the _galzones.dat files, the value in the index column corresponds to that galaxy's row in V2_nsa_v1_0_1_gal.txt. Guidance on how to use these catalogs can be found at https://vast.readthedocs.io/en/latest/. <strong>VoidFinder</strong> VoidFinder-nsa_v1_0_1_main_comoving_holes.txt VoidFinder-nsa_v1_0_1_main_comoving_maximals.txt <strong>V<sup>2</sup></strong> V2_nsa_v1_0_1_gal.txt <strong>VIDE pruning</strong> V2_VIDE-nsa_v1_0_1_galzones.dat V2_VIDE-nsa_v1_0_1_zonevoids.dat V2_VIDE-nsa_v1_0_1_zobovoids.dat <strong>REVOLVER pruning</strong> V2_REVOLVER-nsa_v1_0_1_galzones.dat V2_REVOLVER-nsa_v1_0_1_zonevoids.dat V2_REVOLVER-nsa_v1_0_1_zobovoids.dat
