We present multicolor, optical--infrared photometry from the Hubble Deep Field North (HDF-N), combining HST NICMOS and WFPC2 imaging data with ground--based K--band photometry from KPNO. New wide--field NICMOS maps of the HDF (Dickinson et al. 1999) provide deep, high resolution imaging and photometry at 1.1mu m and 1.6mu m which complement the four band (0.3--0.8mu m) optical data from WFPC2. We extend this to 2.2mu m using ground--based K--band imaging, using an optimized template fitting technique similar to that of Fernandez--Soto et al. (1998). The resulting 7--band photometry greatly extends the wavelength baseline for studying faint HDF galaxies. We present color--magnitude and color--color diagrams for the whole HDF galaxy sample, along with spectral energy distributions for selected objects, and discuss the implications of these data for galaxy properties at high redshift.
