Mueang Soi (Thai: เมืองสร้อย) was a city-state of the Lawa people on the boundary of the present-day Tak province and Lamphun province of Thailand. It may have existed at least from 1126 to the 16th or 18th century when it was destroyed by Burmese or Siamese armies.

The ruins of Mueang Soi have been submerged since 1964 due to the operation of the Bhumibol Dam.
