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 $256 \times 256$ NIR array based spectrometer. In paper I (Ranade et al. 2004), H-band spectra of 135 stars at a resolution of $\sim 16$\AA & paper II (Ranade et al. 2007), K band spectra of 114 stars at a resolution of $\sim 22$\AA were 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 $\sim 12.5$\AA in 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/$\sim$voi/NIR\_Header.html
