The name Isang has been used for sixteen tropical cyclones worldwide: fifteen in the Western Pacific Ocean and one in the South-West Indian Ocean. All of the Western Pacific cyclones were named by either the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) or its predecessor, the Philippine Weather Bureau, and the South-West Indian Ocean cyclone was named by Météo-France.
