We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts, and stellar parameters derived from the analysis of the multiwavelength data. The catalog contains 35445 sources over the 171arcmin^2^ of the CANDELS F160W mosaic. The 5{sigma} detection limits (within an aperture of radius 0.17") of the mosaic range between H=27.8, 28.2, and 28.7 in the wide, intermediate, and deep regions, which span approximately 50%, 15%, and 35% of the total area. The multiwavelength photometry includes broadband data from the UV (U band from KPNO and LBC), optical (HST/ACS F435W, F606W, F775W, F814W, and F850LP), near-to-mid IR (HST/WFC3 F105W, F125W, F140W, and F160W; Subaru/MOIRCS Ks; CFHT/Megacam K; and Spitzer/IRAC 3.6, 4.5, 5.8, and 8.0{mu}m), and far-IR (Spitzer/MIPS 24{mu}m, HERSCHEL/PACS 100 and 160{mu}m, SPIRE 250, 350 and 500{mu}m) observations. In addition, the catalog also includes optical medium-band data (R~50) in 25 consecutive bands, {lambda}=500-950nm, from the SHARDS survey and WFC3 IR spectroscopic observations with the G102 and G141 grisms (R~210 and 130). The use of higher spectral resolution data to estimate photometric redshifts provides very high, and nearly uniform, precision from z=0-2.5. The comparison to 1485 good-quality spectroscopic redshifts up to z~3 yields {Delta}z/(1+z_spec_)=0.0032 and an outlier fraction of {eta}=4.3%. In addition to the multiband photometry, we release value-added catalogs with emission-line fluxes, stellar masses, dust attenuations, UV- and IR-based star formation rates, and rest-frame colors.
