Oman–Thailand relations is the official relationship between Oman and Thailand.

Omani traders, as part of Arab traders, developed healthy tie with the Siamese and even facilitated to the establishment of a Persian/Arab Muslim community that would remain in Thailand for centuries.

Being two similar royal states, Oman and Thailand have sought to take advantage of this link.
