Tala Mi Thiri (Burmese: တလမည်သီရိ, pronounced [təla̰ mì θìɹḭ]; also တလမေသီရိ) was a princess of Martaban–Hanthawaddy Kingdom.
The royal family moved to the dynasty's ancestral home Donwun, about 100 km north of Martaban.
Though not of royal lineage, Maru was a wealthy son of a court minister, and offered 5 viss (8.16 kg) of gold in dowry.
The king had fond memories of Maru's father, who had died in action in his service, and gave his permission.
The king's health had been deteriorating, and he had begun giving day-to-day duties to his sister, one person he trusted.
The chronicle reports that Maru began an affair with the much older Maha Dewi about three years into the marriage.
In 1383, her 15-year-old half-brother Binnya Nwe raised a small rebellion out of Dagon with help from opposing factions of the court.
The Razadarit Ayedawbon states that Maha Dewi collapsed when she saw Maru and Thiri tied to the pole.
