Pan Pan or Panpan is a lost small Hindu Kingdom believed to have existed around the 3rd to 7th Century CE. It is believed to have been located on the east coast of the Malay peninsula, with opinion varying from somewhere in Kelantan or Terengganu, Malaysia to the vicinity of Amphoe Phunphin, Surat Thani Province, Thailand. It is speculated to be related to Pan tan i (the Pattani Kingdom), which occupied the same area many centuries later, and has some differences in culture and language to other Malay regions nearby.
