Iranian migration to Thailand (Persian: مهاجرات ایرانیان به تایلند, romanized: Mohājerat-e Irāniyān be Tāyland) began as early as the 17th century.

There is a community of Thai people of Iranian descent who still practice Shia Islam in many districts throughout Bangkok, such as Yan Nawa, Bueng Kum, Saphan Sung, and Min Buri, as well as parts of Chachoengsao Province.

They are recorded in some memoirs of their fellow merchants, the Dutch East India Company, as well as in the Safine-ye Solaymani ("Ship of Solayman"), an account of a Persian embassy to King Narai.

[6] A notable Persian work that was translated into Thai was Nithan Sibsawng Liam (Tale of the Twelve Angels), which was mostly drawn from the Shahnameh.

[8] However, due to numerous incidents of methamphetamine smuggling, Iranians coming to Thailand fall under heavy suspicion from police.
