We present a catalog of J-band spectra for ss fundamental MK standard stars observed at a resolving power of R similar to 3000. This contribution serves as a companion atlas to the K-band spectra recently published by Wallace & Hinkle and the H-band atlas by Meyer and coworkers. We report data from 7400 to 9550 cm(-1) (1.05-1.34 mu m) for stars of spectral types O7-M6 and luminosity classes I-V as defined in the MK system. In reducing these data, special care has been taken to remove time-variable telluric features of water vapor. We identify atomic and molecular indexes that are both temperature and luminosity sensitive that aid in the classification of stellar spectra in the J band. In addition to being useful in the classification of late-type stars, the J band contains several features of interest in the study of early-type stellar photospheres. These data are available electronically for anonymous FTP in addition to being served on the World Wide Web.
