In this letter we have derived the Jeans length in the context of the Kaniadakis statistics. We have compared this result with the Jeans length already obtained in the nonextensive Tsallis statistics (Jiulin D., Phys. Lett. A, 320 (2004) 347) and we discussed the main differences between these two models. We have also obtained the κ-sound velocity. Finally, we have applied the results obtained here to analyze an astrophysical system.
