This is a list of islands of Thailand. Notice that the names are usually preceded with a Ko (Thai เกาะ, also often romanized as Koh, Go or Goh), the Thai word for island. Thus the English names of the island should not have an additional island in their name, or the Ko has to be left out.

Note that many maps spell Thai names differently. For example, Ko Mak may be seen as Koh Mak, Koh Maak or even Koh Mark. To help search engines, the list also contains alternative names used on some maps in parentheses.
