We present the Cassini Atlas Of Stellar Spectra (CAOSS), comprising of near infrared low-resolution spectra of bright stars recovered from space-based observations by the Cassini spacecraft. The atlas is dominated by red giant stars, but also contains spectra of nearby bright stars from many other spectral classes. The spectra presented are free of all spectral contamination caused by the Earth's atmosphere, including the detrimental telluric molecular bands which put parts of the near infrared spectrum out of reach of terrestrial observations. With a single instrument, a spectro-photometric dataset is recovered that continuously spans the near infrared from 0.8 to 5.1 microns. Spectra have been calibrated into absolute flux units after careful characterisation of the instrumental spectral efficiency. Spectral energy distributions for most stars match closely with literature values. All final data products have been made available online.
