The Indian Grey Mongoose is found from Saudia Arabia, Bahrain, Kuwait, Iran, Afghanistan, Pakistan, India, Sri Lanka, Nepal, and Indonesia, and has been introduced on Japan (Corbet and Hill, 1980; Wells 1989; Wozencraft 2005). This species does not occur on the Ryukyu Islands or Mauritius; the possible records on these islands are only confusion with Herpestes javanicus perpetuated in the literature (S. Roy pers. comm.). The species' elevation range is from 0 to approximately 2500 m (Divya Mudappa pers. comm.).
