The Indian Ocean Naval Symposium (IONS) is a series of biennial meetings between the littoral states of the Indian Ocean region. It provides a forum to increase maritime security cooperation, discuss regional maritime issues, and promote friendly relationships among the member states.[1][2][3][4]
The symposium was first held in 2008 with India as host. The chairmanship and location of the Symposium rotates between the various member states.[5][6][7][8] Each term of chairmanship is two years.[9]

It is a voluntary initiative among the navies and maritime security agencies of the member nations. In addition to the symposiums, numerous other activities like workshops, essay competitions and lectures are also held under the umbrella of the organization.[1]
