List of islands of Thailand

This is a list of islands of Thailand.

This list is incomplete; you can help by expanding it.

Thailand has hundreds of islands both in the Gulf of Thailand and in the Andaman Sea. All of the islands of Thailand are coastal islands. The central area of the Gulf of Thailand is free of islands, so that Thailand has no islands located in the open sea far from the coast. Formerly most of the islands in Thailand were uninhabited, but in recent times many have been developed as tourist resorts.

Some of the island groups in Thailand come in clusters of numerous individual islands; Phang Nga bay has 67, the Mu Ko Chang National Park has 52, Tarutao National Marine Park has 51, and Mu Ko Ang Thong National Park has 42. Owing to the large amount of islands in Thailand the list below is not all-inclusive.

Notes:
1. In Thai, the names of islands are usually preceded with the word Ko, the Thai word for island. This word is often alternately romanized as Koh, Go or Goh. Thus English language references to the names of the Thai islands should not have an additional island in their name, or else the Ko should be left out. For example, “Ko Phi Phi Island” would be redundant, since Ko Phi Phi already means “Phi Phi Island”

2. Various maps commonly spell Thai names differently, using different transliterations. For example, Ko Mak may be seen as Koh Mak, Koh Maak or even Koh Mark. This list gives precedence to the Royal Thai General System of Transcription favored by the Government of Thailand, for the English-based Thai transcription is now becoming obsolete.

To help in using search engines, the list also contains alternative names (used on some maps) either in the “Alternate spellings” column, or in parentheses.
