We have matched 358,046 objects in 143 deg 2 of overlap between the Galaxy Evolution Explorer ( GALEX ) and the Sloan Digital Sky Survey (SDSS). This Letter provides matching statistics at Medium Imaging Survey and All-sky Imaging Survey depths for SDSS-classified stars and galaxies as well as spectroscopic star, galaxy, and QSO subsamples. Distributions of magnitudes, redshifts, and colors are provided. Near-ultraviolet (NUV)-based color-color diagrams reveal (1) the segregation of main-sequence, horizontal-branch, subdwarf, white dwarf, M dwarf, and M dwarf-white dwarf binary stellar populations, (2) a bimodal distribution of galaxies, and (3) the higher signal quality of the GALEX NUV compared to the SDSS u band.
