Abstract. This paper is the third in the series of papers published on near infrared (NIR) stellar spectral library by Ranade et al. (2004 & 2007). The observations were carried out with 1.2 meter Gurushikhar Infrared Telescope (GIRT), at Mt. Abu, India using a NICMOS3 HgCdTe 256 X 256 NIR array based spectrometer. In paper I (Ranade et al. 2004), H-band spectra of 135 stars at a resolution of~16 Ao & paper II (Ranade et al. 2007), K band spectra of 114 stars at a resolution of ~22 Aowere presented. The J-band library being released now consists of 126 stars covering spectral types O5-M8 and luminosity classes I-V. The spectra have a moderate resolution of 12.5 A oin the J band and have been continuum shape corrected to their respective effective temperatures. The complete set of library in near-infrared (NIR) will serve as a good database for researchers working in the field of stellar population synthesis. The complete library in J, H & K is available online at: http://vo.iucaa.ernet.in/voi/NIR Header.html
